Abstract:
1. An injection molded article comprising a thermoplastic component and a thermoplastic silicon-based polymer process additive component, wherein the weight percent of thermoplastic silicone-based polymer process additive component based on the total weight of the article ranges from 0.1 wt % to 1.0 wt %, and further wherein the thermoplastic silicon based polymer process additive component is selected from: (a) at least one copolymer comprising at least two repeat units of Formula I-a: (b) at least one copolymer comprising at least two repeat units of Formula I-b: (c) at least one copolymer comprising at least two repeat units of Formula II: (d) and combinations thereof, wherein for Formulas I-a and I-b each R and further wherein for Formula II each R is an alkyl moiety having about 1 to 12 carbon atoms; each Y is a polyvalent radical; each D is selected from hydrogen, an alkyl radical of 1 to 10 carbon atoms, phenyl, and a radical that completes a ring structure including B or Y to form a heterocyclic; B is a polyvalent radical selected from alkylene, aralkylene, cycloalkylene, phenylene, polyalkylene oxide, and mixtures thereof; Z is a polyvalent radical selected from arylene, aralkylene, alkylene, cycloalkylene, and mixtures thereof; m is an integer from 0 to 1000; n is greater than or equal to 1; and p is greater than or equal to 5.
