The present 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 one ion liquid. Said polymer composition is characterized in that the crystallization point relative to non-additivated polymer compositions is substantially reduced. 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.

Polymer composition having delayed crystallization behavior, additive composition that influences the crystallization behavior, method for lowering the crystallization point, and use of an additive composition

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.
