The polymers made by addition polymerization from two different monomers are termed as

A

addition polymers

B

copolymers

C

condensation polymers

D

homopolymers

Text Solution

Verified by Experts

The correct Answer is:
B
Addition polymers are formed when monomer molecules possessing double or triple bonds undergo repeated addition,. They are of two kinds. The addition polymers formed by the polymerisation of a single monomeric species are known as homopolymers e.g. polyethene while the addition polymers made by addition polymerisation form two different monomers are termed as copolymers, e.g., Buna - S rubber.
On the other hand, the condensation polymers are formed when two different bi-functional monomeric units undergo repeated condensation reactions. Such polymers are always copolymers

Which is a polymer of three different monomers?

Polymers are high molecular mass substances consisting of large number of repeating structural units derived from simple molecules. The polymers formed from one type of monomers are called homopolymers and those formed from two or more different monomers are called copolymers. Depending upon the molecular forces between monomers, polymers may be classified as elastomers, fibers, thermoplastic and thermosetting polymers. The polymers may be formed simply by addition of monomers called addition polymers or by combination of two or more monomers by elimination of simple molecules, called condensation polymers. What is the primary structural feature necessary for a monomer to form condensation polymer?
