Abstract
The synthesis was performed of grafted copolymers of acrylic acid on low molecular weight polyethylene in the presence of benzoyl peroxide in o-xylene solution. The formation of copolymers was proved by the methods of functional analysis of carboxyl groups and FTIR spectroscopy. The patterns of synthesis are shown, which made it possible to obtain graft copolymers in a wide range of compositions. X-ray diffraction analysis demonstrated that the presence of acrylic acid units in the copolymer leads to a decrease in the crystallinity of the copolymers compared to the initial low molecular weight polyethylene.
