    Abstract: Water-emulsifiable hard waxes consisting of homogeneous terpolymers of ethylene with-based on weight of terpolymer-from 1 to 8% by weight of C3-C8-olefinically unsaturated carboxylic acids and from 0.5 to 10% by weight of C1-C12-alkyl esters of such unsaturated carboxylic acids and having a Staudinger index, determined according to DIN 53,728, of from 5 to 55, an acid number of from 8 to 62 and a Höppler hardness, measured by DFG standard method M-III-9a(57), at 23 DEG C., of from 250 to 800 bar, are obtained by copolymerizing ethylene with olefinically unsaturated C3-C8-carboxylic acids and esters of such acids with C1-C12-alkanols in a continuous process in the presence of a free radical initiator at from 150 DEG to 300 DEG C. under a pressure of from 1,000 to 3,000 bar, using a weight ratio of ethylene:acid:acrylate of from 500:1:1 to 20:1:1, in a one-phase polymerization medium in which the monomers are soluble, in the presence of from 0.01 to 8% by weight, based on the sum of the monomers, of a regulator, from 3 to 25% by weight of the ethylene being converted and the copolymer formed being removed continuously from the reaction zone.

    Abstract: The invention relates to a thermoplastic moulding composition comprising A) a (co)polymer in a proportion of from 40 to 99 % by weight, based on A) and B), which contains at least 50 % by weight, based on A), of a copolymerised vinylaromatic monomer, and B) a soft component in a proportion of from 1 to 60 % by weight, based on A) and B), which comprises a graft base and a graft shell, where the graft base is built up from, in each case based on the graft base, b1) from 40 to 99.5 parts by weight of ethylene, b2) from 0.5 to 30 parts by weight of an acrylate of tricyclodecenyl alcohol and b3) from 0 to 50 parts by weight of at least one ethylene-copolymerisable monomer, and where the graft shell is built up from at least one monomer from the group consisting of vinylaromatic and ethylenically unsaturated monomers. The moulding composition may contain conventional additives and is used to produce mouldings.
