Abstract : Fireproof polyester resins were produced by using polyethylene glycol maleate tetrachlorophthalate and various phosphorus-containing monomers. The peculiarities of hardening polyester resins containing chlorine with organophosphorus substances were investigated and it was determined that from 88 to 90 percent of phosphorus-containing dimethacrylates pass over to the gel fraction when hardened at room temperature, whereas only 22 to 29 percent of vinyl and allyl derivatives of phosphoric acid pass to the gel fraction. It was shown that phosphorus-containing resins and glass-fiber-reinforced plastics have good physicomechanical characteristics and are sufficiently heat and flame resistant. (Author)
