ABSTRACT:
Unsaturated, linear polyesters having flame-retarding properties are obtained by polycondensing unsaturated dicarboxylic acids, optionally mixed with aromatic dicarboxylic acids and aliphatic diols, with brominated and/or chlorinated 1,3-di-(hydroxyalkyl)-benzimidazolone compounds. The new, unsaturated polyesters can be polymerized easily, also when mixed with other polymerizable monomers, and give moulding materials having flame-retarding properties.
