Polymer Technology
Antioxidants are added to rubber to protect it from the attack of light, heat & atmospheric ozone. Which of the following is an antioxident used in rubber?
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
Greater the degree of cross-linking in the polymer, lesser is its solubility
