Abstract
Flame-resistant cross-linked polyester resins are prepared by polycondensing one or more [alpha],#-unsaturated polycarboxylic acids or anhydrides thereof and optionally one or more polycarboxylic acids non-polymerizable with ethylenically unsaturated monomers, or anhydrides thereof, with 2,3-dibromo-2-butene- 1,4-diol, and optionally with one or more other polyols, dissolving the polycondensate thus obtained in one or more ethylenic monomers polymerizable with the [alpha],#-unsaturated polycarboxylic acid residues, and cross-linking by polymerization in the presence of a catalyst consisting of from 0À005 to 4% by weight with respect to the reactants, of an organic peroxide or hydroperoxide. In the examples the polyester is prepared from phthalic anhydride, tetrahydrophthalic anhydride, maleic anhydride, 2,3-dibromo-2-butene-1,4-diol, and ethylene glycol and cross-linked with styrene in the presence of benzoyl peroxide and tris-(chloroethyl) phosphate.
