Obtaining unsaturated polyester resins using recycled polyethylene terephthalate

Abstract

A method for obtaining an unsaturated polyester resin based on recycled polyethylene terephthalate has been developed. The process of curing an unsaturated polyester resin under the action of styrene, a peroxide compound (Butanox 50M) and an accelerator (cobalt stearate and dimethylaniline) has been studied. The physical and mechanical properties of polymeric materials based on the developed resin have been studied. It has been established that their strength depends on the mass fraction of recycled polyethylene terephthalate in the oligoether polyol used in the synthesis.
