Swelling tendency or solubility of polymers in a particular solvent decreases with increase in molecular weight of the solvent
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
Greater the degree of cross-linking in the polymer, lesser is its solubility
