Thermoplastics of polyalkylene terephthalates impact modified with

An impact-resistant thermoplastic molding material which contains, based in each case on A+B, from 80 to 50% by weight of a hard matrix A of polystyrene having a molecular weight M.eta. of from 150,000 to 200,000 and from 50 to 20% by weight of a soft phase B which is uniformly distributed in the hard matrix and has a median particle diameter d.sub.50 (volume average) of from 1 to 10 .mu.m, and can be obtained by polymerizing styrene in the presence of an elastomeric grafting base, advantageously has a molecular weight of the grafted branches of from 1.1 to 1.35 times the molecular weight of the hard matrix, and the degree of grafting is from 50 to 100%.

Impact-resistant thermoplastic molding material and its use

Thermoplastics impact modified with functionalized polymers and use

Homo- or copolymers which have terminal mercapto groups, are composed of one or more monomers from the group consisting of butadiene, isoprene and styrene and are obtained by anionic polymerization of one or more of the stated monomers in the presence of one or more organolithium compounds followed by reaction (of the living anions) with an episulfide of the general formula I ##STR1## where R is hydrogen, alkyl of 1 to 18 carbon atoms or aryl of 6 to 10 carbon atoms, with the formation of one or more primary or secondary mercapto groups at the end of the polymer chain(s) are prepared by a process in which a thiolcarboxylic acid of the general formula II ##STR2## where R.sup.1 is hydrogen, alkyl of 1 to 10 carbon atoms or --CH.sub.2 --COOH and R.sup.2 is 0 or from 1 to 10 CH.sub.2 units, is added directly to the resulting reaction mixture in an amount of from 0.5 to 2 moles of the thiolcarboxylic acid per mole of episulfide, and the reaction product is subjected to an aftertreatment
