Abstract
Process for preparing polyester resins, suitable for obtaining crosslinked polyesters of difficult saponification, characterized in that it comprises mixing, in the presence of polymerization initiators and inhibitors, in the usual amounts, 1) 40 to 90% by weight of an unsaturated polyester which, in turn, consists of a) 30 to 80% by weight of α, β-ethylenically unsaturated dicarboxylic acid residues, of which up to 70 mol-% may be substituted by saturated dicarboxylic acid residues and up to 10 mol-% by mono- or trifunctional carboxylic acids, b) 20 to 70% by weight of residues of 2-alkylpropanediols-1,3, carrying the alkyl group 1 to 6 carbon atoms, or of a cyclohaxyl residue, c) 0 to 50% by weight of residues of other diol components, of which up to 10 mol-% may be substituted by mono- or trivalent alcohols; with 2) 10 to 60% by weight of copolymerizable compounds.
