Abstract
Process to prepare polymerizable, waste-free, flowable and suitable for injection molding masses, based on ethylenically unsaturated polyesters, copolymerizable and thermoplastic monomers, characterized in that fumaric acid, or maleic acid, or its anhydrides are polycondensed with approximately glycol equivalents of general formula HO-CH2-R-CH2-OH where R means an alkylene of formula (CH2) z, where z = 1-18, or dialkyl derivatives of these alkylene moieties, where the alkyl substituents are found in the The same carbon atom, or cycloalkylene residues, at higher temperatures, since) 24-70% by weight of the polyester, thus obtained, dissolves in b) 20-75% by weight of styrene, and the solution obtained is homogenize with c) 1 - 30% by weight of polycarbonate, polyamide, polyvinyl alcohol, polyvinyl alcohol acetals, polyvinyl chloride and/or polyethylene by stirring, kneading or any other mechanical method. only, under the condition of the sum of a), b) and c) complete 100%.
