  • Clarified polypropylene articles with improved optical properties and/or increased temperature of crystallization
    Patent number: 9029446
    Abstract: Disclosed are polypropylene articles with improved optical properties and/or an increased temperature of crystallization comprising a polypropylene resin and uniformly dispersed therein from about 1 ppm to about 10 ppm of one or more polycyclic organic pigments selected from blue, green, magenta, red, yellow, orange and violet polycyclic organic pigments and from about 50 ppm to about 250 ppm of one or more aromatic trisamide nucleating agents, where the ppm levels are by weight based on the weight of the polypropylene resin. The polypropylene is for example polypropylene homopolymer. The articles exhibit reduced haze, increased temperature of crystallization and excellent clarity.
