Polymer Technology
In step growth polymerisation, generally only one type of reaction & some basic mechanism is involved. Step growth polymerisation reaction is not involved in the manufacture of
Greater the degree of cross-linking in the polymer, lesser is its solubility
High molecul ar weight polymers on dissolving gives solution of very low viscosity
Polymers having more aliphatic character are more soluble in aliphatic solvents, while those polymers having more aromatic character are more soluble in aromatic solvents
Swelling tendency or solubility of polymers in a particular solvent decreases with increase in molecular weight of the solvent
