graft copolymerization

Graft copolymerization onto a solid polymer surface is an eff ective tool for its modifi cation. A large number of works have been published and require systematization. A search and review of English-language scientifi c literature devoted to the graft copolymerization of acrylic monomers onto a polymeric solid-phase surface have been carried out. Grafting onto plates and fi lms, as well as fi bers and colloidal particles, is considered.

A search and review of English-language scientifi c literature about the graft copolymerization of acrylic monomers onto a solid-phase polymeric surface has been carried out. Grafting onto plates and fi lms of high- and low-density polyethylene is considered. The monomers used were acrylic and methacrylic acids, glycidyl acrylate and glycidyl methacrylate, etc., and the main method was UV photopolymerization with an initiator – benzophenone, etc.

The method presents obtaining hydrosoluble graft copolymer of complicated structure based on сhitosan, acrylamide (AM), sodium 2-acrylamido-2-methylpropane sulfonic (АМPS-Na) in order to obtain fl ocсulant which is resistant to salt of transition metals and heat temperature, and in order to use it as a reagent for oil production processes.
