<p>To allow inhibition of styrene evaporation from an unsaturated polyester resin during curing, there is present in the resin a small amount (0.1 to 5 % by weight) of a lone-chain vinyl compound of the formula wherein R is a straight-or branched-chain substituted or unsubstituted aliphatic C6-C24 hydrocarbon, Y = H or CH3, N = zero or 1, X = or -0-. Preferred such compounds are lauryl and stearyl methacrylate. The resins are made by admixture of the selected compound(s) with the conventional other components of the resin.</p> |
