Question

1- what does the degree of polymerization indicate?

2- Cite the primary differences between addition and condensation polymerization techniques?

Answer 1

1-The degree of polymerization is the number of monomeric units present in a polymers. If we divide, molecular weight of the polymer by the molecular weight of the monomeric unit we will get the degree of polymerization.

2-The primary Difference Between Addition and Condensation Polymerization is that Addition Polymerization involves only one monomer and does not lead to a loss in smaller molecules e.g PVC and Teflon ,while Condensation Polymerization involves two different kinds of monomers and lead to loss of simple molecules like HCl etc. for example nylon, bakelite.
