Polymer Technology
Cellulose acetate has very high film permeability among all the polymers of the order of 5000 gm/100 m². Which of the following polymers has the maximum film elongation (of the order of 100%) ?
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
Greater the degree of cross-linking in the polymer, lesser is its solubility
Polymers having more aliphatic character are more soluble in aliphatic solvents, while those polymers having more aromatic character are more soluble in aromatic solvents
