Polymer Technology
Natural rubber is obtained from latex, which is a colloidal dispersion of rubber in water. Which of the following is used as a coagulant in latex?
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
High molecul ar weight polymers on dissolving gives solution of very low viscosity
