Polymer Technology
Plasticisers are high boiling liquids added to plastic polymers to impart toughness and flexibility at ordinary temperature. Which of the following is not a plasticiser?
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
High molecul ar weight polymers on dissolving gives solution of very low viscosity
Swelling tendency or solubility of polymers in a particular solvent decreases with increase in molecular weight of the solvent
