Abstract

AbstractCopolymerization of 2‐hydroxyethyl methacrylate (HEMA) with methyl methacrylate (MMA) was carried out in bulk in nitrogen atmosphere at 70°C using 0.2% benzoyl peroxide as initiator. Fractionation of the copolymers was done by precipitation method. The fractions were characterized by viscosity, NMR, IR and elemental analysis. Thermal behaviour of various fractions was investigated by dynamic thermogravimetry. Thermal stability of various fractions was not significantly influenced by the change in intrinsic viscosity.
