Abstract
The invention relates to a polymer composition, which contains or consists of a matrix of at least one thermoplastic polymer capable of crystallization and, incorporated therein, at least one azine dye and at least mono-, di-, tri-, and/or tetravalent metal salt. Said polymer composition is characterized in that the crystallization point thereof is considerably reduced in comparison with polymer compositions having no additives or a composition containing only an azine dye or a metal salt as an additive. The invention further relates to a corresponding additive composition for the crystallization and/or for the lowering of the crystallization point of thermoplastic polymers or polymer compositions capable of crystallization.
