Abstract: A thermoplastic moulding composition containing from 2 to 60% by weight of a graft copolymer A and from 40 to 98% by weight of a copolymer B. The graft copolymer is prepared by graft copolymerisation of a mixture of a vinylaromatic monomer and acrylonitrile and/or a (meth)acrylic ester ((meth)acrylate) onto an elastomer component containing at least one alkyl acrylate. The elastomer component is prepared using from 0.1 to 20% by weight of at least one diallyl ester of a saturated aliphatic dicarboxylic acid having 4 to 12 carbon atoms. The copolymer B is formed from a vinylaromatic monomer and/or acrylonitrile and/or a (meth)acyrlic ester. The moulding composition may contain conventional additives in effective amounts and is used for the production of mouldings.

Abstract: 1. A process for the production of cellular or non-cellular polyurethane elastomers from organic polyisocyanates, relatively high molecular weight polyhydroxy compounds and chain extenders in the presence or absence of catalysts, blowing agents, auxiliaries and additives, wherein there are used as polyhydroxy compounds polyester polyols obtained by polycondensation of an organic dicarboxylic acid with an alcohol mixture consisting of 40 to 100% by weight, based on the alcohol mixture, of a diol mixture which in its turn consists essentially of (a) 10 to 30% by weight of 1,4-butanediol, (b) 40 to 60% by weight of 1,5-pentanediol, and (c) 15 to 35% by weight of 1,6-hexanediol, the percentages by weight being based on the total weight of the diol mixture, and 60 to 0% by weight, based on the alcohol mixture, of a dihydric alcohol selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,8-octanediol, neopentyl glycol, 1,4-bis-(hydroxymethyl)cyclohexane, 2-methyl-1,3-propanediol, 3-methyl-1,5-pentanediol, diethylene glycol, dipropylene glycol and dibutylene glycol, or 90 to 98% by weight, based on the alcohol mixture, of the above diol mixture, and 2 to 10% by weight, based on the alcohol mixture, of a trihydric and/or tetrahydric alcohol.

Abstract: N-Alkylpiperidines or N-alkylpyrrolidines are obtained by hydrogenating a corresponding N-alkyldicarboxylic acid imide over a fixed catalyst by first working to only partial conversion, for example of about 50%, and distilling off the required product together with water from the partially converted mixture, where appropriate with recycling of the unconverted remainder.
