Difference Between Homopolymer and Copolymer

The main difference between homopolymer and copolymer is that homopolymer is the polymer that is made up of only one type of monomer while copolymer is the polymer that is made up of two different types of monomers…

Homopolymer vs. Copolymer

Homopolymer is the polymer that is made up of one type of monomer while copolymer is the polymer that is made up of two different types of monomers. The homopolymer generally has a simple structure, while the copolymer generally has a complex structure. The homopolymer is produced by addition polymerization while the copolymer is produced by condensation polymerization. Homopolymer produced by the repetition of one type of monomer, while copolymer produced by the copolymerization of two different types of monomers. The homopolymer is the single polymer while the copolymer is the bipolymer. The homopolymer has high levels of crystallinity while the copolymer has low levels of crystallinity. The homopolymer has less good mechanical properties, while the copolymer has better mechanical properties. The homopolymer has short-term stability, while the copolymer has long-term stability. Homopolymer grades are less attractive, while copolymer grades are more attractive. The homopolymer has less good oxidation resistance, while the copolymer has better oxidation resistance. Homopolymer has less good dimensional properties, while copolymer has better dimensional properties.Homopolymer grades have low moisture absorption, while copolymer is less vulnerable to hydrolysis in hot water. During homopolymer formation, monomers must have a single or double bond, while the copolymer need not have an unsaturation in a compound. The homopolymer is not divided into different classes, while the copolymer has been divided into several classes. while copolymer grades are more attractive. The homopolymer has less good oxidation resistance, while the copolymer has better oxidation resistance. Homopolymer has less good dimensional properties, while copolymer has better dimensional properties.Homopolymer grades have low moisture absorption, while copolymer is less vulnerable to hydrolysis in hot water. During the formation of the homopolymer, the monomers must have a single or double bond, while the copolymer is not required to have an unsaturation in a compound. The homopolymer is not divided into different classes, while the copolymer has been divided into several classes. while copolymer grades are more attractive. The homopolymer has less good oxidation resistance, while the copolymer has better oxidation resistance. Homopolymer has less good dimensional properties, while copolymer has better dimensional properties.Homopolymer grades have low moisture absorption, while copolymer is less vulnerable to hydrolysis in hot water. During the formation of the homopolymer, the monomers must have a single or double bond, while the copolymer is not required to have an unsaturation in a compound. Homopolymer is not divided into different classes, while the copolymer has been divided into several classes. while the copolymer has better dimensional properties. Homopolymer grades have low moisture absorption, while copolymer is less vulnerable to hydrolysis in hot water.

What is homopolymer?

Homopolymer is the polymer that is made up of only one type of monomer. It is produced by addition polymerization. The monomer must have a single or double bond. The homopolymer has a simple structure. The homopolymer has less good mechanical properties. The homopolymer has less good oxidation resistance. The homopolymer has less good dimensional properties. It also has high levels of crystallinity. Homopolymer grades are less attractive. Homopolymer grades absorb moisture. The homopolymer has short-term stability. The homopolymer has a different chemical structure than the copolymer. The homopolymer has less good mechanical properties, such as tensile strength, stiffness, early creep strength, and impact strength. The homopolymer is opaque and has poor UV resistance, is easily attacked by alkalis and acids, is prone to thermal degradation, and has poor fire behavior. The homopolymer has attractive grades. The homopolymer also has a higher heat distortion temperature. The homopolymer is more susceptible to hydrolysis in hot water. The homopolymer has the highest chance to get the interaction of the polymer chains and thus get the crystal structure. This process also obtains higher melting points. The homopolymer also has low melting points. Homopolymer also formed by a single repeating unit. The homopolymer has attractive grades. The homopolymer also has a higher heat distortion temperature. The homopolymer is more susceptible to hydrolysis in hot water. The homopolymer has the highest chance to get the interaction of the polymer chains and thus get the crystal structure. This process also obtains higher melting points. The homopolymer also has low melting points. Homopolymer also formed by a single repeating unit. The homopolymer has attractive grades. The homopolymer also has a higher heat distortion temperature. The homopolymer is more susceptible to hydrolysis in hot water. The homopolymer has the highest chance to get the interaction of the polymer chains and thus get the crystal structure. This process also obtains higher melting points. The homopolymer also has low melting points. Homopolymer also formed by a single repeating unit. This process also obtains higher melting points. The homopolymer also has low melting points. Homopolymer also formed by a single repeating unit. This process also obtains higher melting points. The homopolymer also has low melting points. Homopolymer also formed by a single repeating unit.

What is copolymer?

Copolymer is the polymer which is made up of two different types of monomers. It is produced by polymer condensation. The monomers must have unsaturation. The copolymer has a complicated structure. The copolymer has better mechanical properties. The copolymer has better oxidation resistance. The copolymer has good dimensional stability. The copolymer has low levels of crystallinity. Copolymer grades are more attractive. It has long-term stability. The homopolymer must have better mechanical properties such as stiffness, high tensile strength, impact strength, early creep resistance. The copolymer is opaque and has poor UV resistance. It can easily attack alkalis and acids and has poor fire behavior. It has a tendency to thermal degradation. It also has higher melting points. The copolymer is less vulnerable to hydrolysis in hot water. It is made up of two different species of monomer. The copolymer has low heat distortion.

Copolymer Classifications

• Statistical copolymer: Polymer formed by repeating units that obey the statistical law.
• Alternating copolymer: Polymer formed by two types of repeated monomers that are arranged alternately in the chain.
• Block copolymer: polymer in which there are repeating units in blocks.

examples

Polyvinyl acetate, polyethylene oxide, etc.
