POLYMER MIXTURE

摘要

Thermoplastic polymer mixture (I), comprising a) 50 99.9 wt. % of a polyamide (II), based on the total weight of polymer in polymer mixture (I) and b) 0.1 - 50 wt. % of a polymer (III), based on the total weight of polymer in polymer mixture (I), whereby the fusion viscosity, measured according to ISO 11443, of polymer (III) at 280°C in the complete shear rate range of from 100 to 20,000 s-1, is at most 75 % of the fusion viscosity, measured according to ISO 11443, of polyamide (II) at 280°C and the interfacial surface tension between a melt of polyamide (II) and a melt of polymer (III) at 280°C, measured according to US Patent Nr. 5,150,607 by the spinning drop method, is in the range from 0 mN/m to 10 mN/m.
