Abstract
A polyester is prepared by heating at least one a ,b -unsaturated dicarboxylic acid or anhydride, or a mixture of dicarboxylic acids or anhydrides of which at least 10 mol. per cent are a ,b -unsaturated, with ethylene oxide, propylene oxide or butylene oxide, or a mixture thereof, in the presence of a catalytic amount of a lithium compound until a product of acid number 20-130 is obtained, then heating this at 200-240 DEG C. for 30 minutes to 6 hours. The preferred anhydride or acid mixtures are phthalic anhydride/maleic anhydride and phthalic anhydride/fumaric acid Other suitable anhydrides for use with a ,b -unsaturated acids or anhydrides are those of succinic, adipic, glutaric, octadecylsuccinic, diglycollic, thiodiglycollic, tetrahydrophthalic, tetrachlorophthalic and other substituted phthalic acids, and those of Diels-Alder adducts of cyclopentadiene and maleic anhydride. The preferred alkylene oxide is propylene oxide. Suitable lithium compounds are the hydroxide, ethoxide, chloride, bromide, carbonate, acetate, nitrate, sulphate and phthalate. The preferred catalyst is lithium hydroxide, in amount 0.05-0.5% by weight of the polyester. The use of initiators, e.g. water, ethylene glycol, propylene glycol, fumaric acid or maleic acid, is desirable. In practice the acids, catalyst and initiator are mixed, and the alkylene oxide is then added at once, or in increments, or continuously during the reaction. Different acids may be added at various stages of the reaction, which may be held at 125-135 DEG C. during the addition of alkylene oxide or allowed to rise from 90 DEG to 200 DEG C. It is usually desirable to add further alkylene oxide after the heating to 200-240 DEG C., to bring the acid number to 10-40, after which the polyester may be thinned with 20-50% by weight of the composition of a polymerizable monomer containing at least one CH2 = C < group, e.g. styrene or vinyl toluene. The catalyst also may be added incrementally or continuously with the alkylene oxide. In examples, mixtures of phthalic anhydride with maleic anhydride or fumaric acid are heated, with or without water, with propylene oxide in the presence of lithium hydroxide, and the products are mixed with styrene. A comparison example, using sodium hydroxide, is supplied.
