CPC C08K 5/29 (2013.01) [C07C 265/02 (2013.01); C07C 265/14 (2013.01); C08L 77/00 (2013.01); C08J 2300/22 (2013.01)] | 7 Claims |
1. A method of producing a molding comprising a thermoplastic molding composition comprising admixing
A) from 30 to 99% by weight of a thermoplastic polyamide selected from the group consisting of PA 6 and PA 66,
B) from 0.01 to 10% by weight of cyclohexyl trans-1,4-diisocyanate and phenylene 1,4-diisocyanate, and
C) from 0 to 60% by weight of other additional substances,
where the sum of the percentages by weight of A) to C) is 100% and the thermoplastic molding composition is free of polyoxymethylene,
wherein the molding has improved haze, measured in accordance with ASTM D1003, and/or improved clarity, measured in accordance with ASTM D1003, and/or increased laser transparency, measured at a wavelength of 1064 nm by means of a thermoelectric power measurement,
wherein the haze value of the molding, measured in accordance with ASTM D1003, is at least 5% lower than that of a reference polymer composition without component B), measured from a test sample of thickness 1.3 mm,
wherein the clarity value of the molding, measured in accordance with ASTM D1003, is at least 5% higher than that of a reference polymer composition without component B), measured from a test sample of thickness 1.3 mm, and
wherein the laser transparency of the molding, measured at a wavelength of 1064 nm by means of a thermoelectric power measurement, is at least 1% higher than that of a reference polymer composition without component B), measured from a test sample of thickness 1.3 mm.
