Question

What is mean by bifunctional and trifunctional polymers?

Answer 1

Polymers:

• "The term polymer is defined as very large molecules having high molecular mass $({10}^3-{10}^7\mathrm{u})$. These are also referred to as macromolecules, which are formed by joining of repeating structural units on a large scale."
• The polymers are classified on the basis of the functional group numbers attached.

Bifunctional polymer:

• The polymer that is formed by joining bifunctional monomeric units is known as Bifunctional polymer.
• Dacron is a polymer of ethylene glycol and terephthalic acid.

Trifunctional polymer:

• Trifunctional polymer means one having three functional groups in every monomer.
• Examples of trifunctional or polyfunctional monomeric units are glycerine and divinylbenzene.
