Patent number: 4387171Abstract: An unsaturated halogenated or non-halogenated polyester resin composition for open lay-up moulding and containing styrene as an agent for cross-linking during curing additionally contains 0.1 to 5% by weight, based on the total weight of the composition, of at least one C.sub.18-40 .alpha.-olefine compound which is theoretically capable of taking part in the cross-linking reaction.When the composition contains a non-halogenated polyester resin, then the .alpha.-olefine compound itself serves to restrict styrene evaporation from the composition.For halogenated polyester resin compositions, the .alpha.-olefine, although not usually by itself providing such a marked restriction of styrene evaporation, does allow incorporation into the composition of a waxy compound in an amount sufficiently large to achieve the desired styrene evaporation restriction without deterioration of the adhesion properties of the composition during lay-up.Type: GrantFiled: August 21, 1981Date of Patent: June 7, 1983Assignee: Scott Baker Company LimitedInventor: Robert F.

Patent number: 4336169Abstract: An unsaturated polyester resin composition for ambient temperature open lay-up moulding contains styrene as an agent for cross-linking during curing, a wax for preventing air inhibition and a compound for allowing reduction of styrene evaporation. The compound is of the formulaR.sub.1 --X--CH.dbd.CHCOOHwhere R.sub.1 is a straight- or branched-chain substituted or unsubstituted aliphatic C.sub.6 --C.sub.24 hydrocarbon, and ##STR1## Such resin compositions are particularly suitable for producing laminates and the abovementioned compounds serve as adhesion-promoting agents. Incorporation of such compounds into the compositions enables larger amounts of the waxy substances to be included by compensating for the loss of adhesion which would otherwise have arisen from the presence of larger quantities of waxy substance.Type: GrantFiled: December 16, 1980Date of Patent: June 22, 1982Assignee: Scott Bader Company LimitedInventors: George D.
