Polymer string mainly but not exclusively consisting of one or several polymers, characterised in that at least one polymer consists of a thermoplastic material in which at least one alkylbenzyl ester of a 1,2 dicarboxylic acid or one of its derivatives is distributed homogeneously, that the alkyl chain of the alkyl-benzyl ester or one of its derivative+es consists of at least five carbon atoms, and that it is used in a concentration between 0.1 to 5 percent by weight, better between 0.3 to 4 percent by weight, and even better between 0.3 to 1.2 percent by weight. |
