Abstract:
Radical copolymerization of polyethylene glycol maleate with acrylamide and monovinyl ether of
monoethanol amine has been performed for the first time. Radical co- and terpolymerization of the systems
polyethylene glycol maleate with acrylamide and monovinyl ether of monoethanol amine has been studied.
Molecular weight of polyethylene glycol maleate has been determined using light scattering and gel permeation
chromatography. The compositions of the polymers and copolymerization constants of the studied systems
have been determined. The composition of the copolymers has been found using gas chromatography.
Kinetic curves show that with increasing molar fraction of acrylamide in the solution the reaction rate and
swelling capacity of the copolymers increase. It has been shown that the composition of terpolymers determined
experimentally differs considerably from the one calculated taking into account obtained constants of
copolymerization. Deviations found are due to various intermolecular interactions in these systems. The possibility
of controlling the properties of network copolymers of polyethylene glycol maleate by changing external
factors has been studied. Swelling capacity of the copolymers investigated was studied using gravimetric
method.
