Abstract

The present invention relates to compositions which may be cured by radical polymerization at room temperature and contain PA0 A) 20 to 100 parts by weight of .alpha.,.beta.-ethylenically unsaturated polyesters which are the reaction products of PA0 a) a dicarboxylic acid component containing i) 40 to 100 carboxyl equivalent % of .alpha.,.beta. ethylenically unsaturated dicarboxylic acids and/or their anhydrides and ii) 0 to 60 carboxyl equivalent % of dicarboxylic acids and/or their anhydrides other than those set forth in i) with PA0 b) an alcohol component containing i) 25 to 100 hydroxyl equivalent % of alkoxylated 2-butene-1,4-diols having an average molecular weight 130 to 400 and ii) 0 to 75 hydroxyl equivalent % of mono- or poly- hydric alcohols having a molecular weight of 32 to 400 other than those set forth in i) wherein the amounts of a) and b) are chosen such that equivalent ratio of carboxyl groups to hydroxyl groups is no more than 1:1, PA0 B) 0 to 80 parts by weight of compounds containing (meth)acryloyl groups and/or vinyl ether groups, wherein the sum of the parts by weight of A) and B) is 100, based on the weight of components A) and B), provided that when compon…
