Abstract

Stabilized epihalohydrin polymer compositions, which may be heated with polyamines to give cross-linked compounds comprise an epihalohydrin polymer, a nitrogen containing anti-oxidant and a lead oxide or a lead salt of an unsaturated aliphatic carboxylic acid, an aromatic carboxylic acid, or carbonic acid, the epihalohydrin polymer being a homopolymer or a copolymer of an epihalohydrin with at least one other epoxide. The polymers contain at least 10% by weight of epihalohydrin monomer units. The composition preferably contains 3% to 25% by weight of the lead compound and 0.1% to 5.0% of anti-oxidant based on the weight of the polymer and in addition large excesses of these constituents, e.g. 100%, may be used. Polymers specified are poly(epichlorohydrin), poly(epibromohydrin), poly(epifluorohydrin), poly(epiiodohydrin), epichlorohydrin-epibromohydrin copolymer, epichlorohydrin-propylene oxide copolymer, epichlorohydrin-cyclohexene oxide copolymer, epichlorohydrin-2 chloro ethyl glycidyl ether copolymer and epichlorohydrin - propylene oxide - allyl glycidyl ether terpolymer. The polymers have molecular weights of at least 40,000. Specified nitrogen containing antioxidants are phenyl-b -naphthylamine, di-b -naphthyl-p-phenylene diamine, sym - di - b - naphthyl - p - phenylene diamine, N - isooctyl - p - aminophenol, the reaction product of diphenylamine and acetone and polymerized trimethyldihydroquinoline. Specified lead compounds are tribasic lead maleate, di-basic lead phthalate, dibasic lead isophthalate, lead dehydroabietate, PbCO3, 2PbCO3.Pb(OH)2, Pb2O, PbO, PbO2, Pb2O3 and Pb3O4. The poly-mers are prepared by reacting epihalohydrin monomer, mixtures of monomers or mixtures of monomer with at least one epoxide at - 80 DEG C. to 250 DEG C. in an inert diluent in presence of an organoaluminium compound which has preferably been treated with a chelating agent. Specified organoaluminium compounds are triethylaluminium, triisobutylaluminium, and diethylaluminium hydride. Cross-linked products are obtained by heating at 120-175 DEG C. the polymer composition with 0.25% to 8.0% by weight of polyamine based on the weight of polymer. Specified cross-linking agents are ethylene diamine, diethylene triamine, hexamethylene diamine, p-phenylene diamine, hexamethylene diamine carbamate, urea, biuret, thiourea, dibutyl thiourea and trimethyl thiourea. Mixtures of polyamines may be used. Other additives include fillers, pigments, plasticizers, extenders and light absorbers. Specified additives are carbon black and a cadmium-barium complex. Many examples describing the cross-linking of the polymer compositions are given.
