CLARIFIED POLYPROPYLENE PRODUCTS WITH IMPROVED OPTIC PROPERTIES AND/OR HIGHER CRYSTALLISATION TEMPERATURE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to polypropylene products with reduced tarnish, higher crystallisation temperature and brightness. Polypropylene product with improved optic properties and/or higher crystallisation temperature contains polypropylene resin and homogenously dispersed in it from approximately 1 ppm to approximately 10 ppm of one or more polycyclic organic pigments, selected from blue, green, purple, red, yellow, orange and violet polycyclic organic pigments and from approximately 50 ppm to approximately 250 ppm of one or more aromatic trisamide nucleating agents, expressed by formula,and where ppm levels are expressed in weight counted per weight of polypropylene resin.EFFECT: invention makes it possible to obtain product, possessing reduced tarnish, higher crystallisation temperature and higher transparency.10 cl, 1 tbl, 2 ex
