| abstract |
The invention relates to a copolymer for producing molded compounds or cast glass for the production of molded bodies having increased dimensional stability under heat, obtainable from the copolymerization of A) one or more ethylenically unsaturated ester compounds of the formula (I), where R 1 is hydrogen or methyl and R 2 a linear or branched alkyl group with 1 to 8 carbon atoms, B) one or more ethylenically unsaturated ester compounds of the formula (II), where R 3 is hydrogen or methyl and R 4 a cyclic group with 8 to 30 carbon atoms, C) one or more ethylenically unsaturated ester compounds of the formula (III), where R 5 is hydrogen or methyl and R 6 and R 7 , independently of each other, are hydrogen or a linear or branched group with 1 to 40 carbon atoms. |
