Abstract
A method of making resin composition having excellent wear properties that includes 50 to 99 wt. % of a polycarbonate resin and from 1 to 50 wt. % of a polyolefin that has been modified with at least one functional group selected from a carboxyl, an acid anhydride, an epoxy groups or mixtures containing at least one of the foregoing functional groups, each based on the total combined weight of the resin composition, exclusive of any filler. The resin composition optionally contains an unmodified polyolefin and/or a bi-functional monomer. The resin composition can be molded into articles having improved wear characteristics. The process is a one-step process that improves the efficiency and/or yield of the resin composition as compared to prior-art two-step processes.
