Polymer Technology
Pick out the wrong statement regarding the solubility characteristics of high polymers.

High molecul ar weight polymers on dissolving gives solution of very low viscosity
Greater the degree of cross-linking in the polymer, lesser is its solubility
Swelling tendency or solubility of polymers in a particular solvent decreases with increase in molecular weight of the solvent
Polymers having more aliphatic character are more soluble in aliphatic solvents, while those polymers having more aromatic character are more soluble in aromatic solvents
