Constants and parameters of radical copolymerization of polyethylene glycol maleate with acrylamide at high conversion degree

Abstract

Radical copolymerization of polyethylene glycol maleate with acrylamide was performed for the first time. Molar mass of polyethylene glycol maleate was determined using light scattering and gel permeation chro- matography. The composition of the copolymers was found using gas chromatography. The kinetics of co- polymerization reaction studied and copolymerization constants were calculated. Kinetic curves show that with increasing molar fraction of acrylamide in the solution the reaction rate and swelling capacity of the co- polymers increase.
