Abstract

A thermoplastic resin composition is disclosed which comprises a matrix polymer, and a combination of a fluoropolymer that can be at least partially encapsulated by an encapsulating polymer, and a filler. Methods for making the thermoplastic resin composition and articles made of such compositions are also disclosed. The composition and article can have improved tensile modulus, ductility and impact properties.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Patent Application Serial No. 10 / 748,393, filed December 30, 2003, which is incorporated herein by reference in its entirety. Background of the Invention [0003] The present disclosure relates to polymer compositions, methods of synthesizing the polymer compositions, and articles made from the compositions. [0004] Many polymer-based articles are prepared by injection molding or other molding methods. In order to obtain good mechanical properties (eg high modulus), many methods have been tried, such as the use of fillers to reinforce the polymer. Different types of fillers are used, such as glass fibers, aramid fibers, carbon fibers and various granular fillers. However, the addition of these fillers generally results in brittle failure of the polymer and can reduce the impact strength of the resin. In the case of aramid fillers, for example, th...
