Abstract
In the manufacture of copolymers of unsaturated polyester resins and unsaturated monomers, the polyester is derived from an alpha-beta-unsaturated dicarboxylic acid and an ether of formula CH2OH.CH(OH).CH2OR or <FORM:0789267/IV (a)/1> where R is the residue of a monohydric phenol of formula R.OH. The alpha-beta-unsaturated dicarboxylic acid may be maleic, fumaric, itaconic or citraconic acid and it may be used in admixture with another polycarboxylic, e.g. phthalic, isophthalic, a Diels-Alder adduct of maleic acid and a conjugated diene (e.g. cyclopentadiene or hexachlorocyclopentadiene) or an acid of formula HOOC(CH2)nCOOH where n=2-12. The ether may be glycerolmonophenyl or monocresol ether, p-tert-butylphenyl glycidyl ether or cresyl glycidyl ether and it may be used in admixture with ethylene-, propylene-, butylene-, polyethylene- or polypropylene-glycol or hexane triol. The polyester may be modified with benzoic acid, acrylic acid or its homologues, fat alcohols, benzyl alcohol or allyl alcohol. The unsaturated monomer may be styrene, vinyl toluene, vinyl xylene, diallyl phthalate, triallyl cyanurate, vinyl acetate, acrylic acid esters, methacrylic acid esters (e.g. methyl methacrylate), allyl alcohol esters or acrylonitrile. Copolymerization may be effected in presence of benzoyl peroxide, cumyl hydroperoxide or methyl ethyl ketone peroxide, if desired in presence of an accelerator, e.g. cobalt naphthenate or a tertiary amine. In examples, there was copolymerized with styrene or vinyl toluene (1), (2) and (4) a polyester from maleic anhydride and glycerol-alpha-monophenyl ether or p-tert-butylphenyl glycidyl ether; (3) a polyester from fumaric acid, sebacic acid and glycerol monophenyl ether; (5) and (6) a polyester from maleic anhydride, cresyl glycidyl ether and sebacic or adipic acid; (7) a polyester from maleic anhydride, sebacic acid, cresyl glycidyl ether and diethylene glycol; (8) a polyester from maleic anhydride, adipic acid, crotonic acid, p-tert-butylphenyl glycidyl ether and hexanetriol. The resin compositions are useful in the production of moulded bodies, glass fibre lamin and lacquer films.
