Method of dispersing fluoropolymers on polycarbonate resins

摘要

Fluoropolymers in the form of solid particles of specified diameter and dispersed in water are added and mixed with polycarbonate resin particles at a rate of 0.1 to 9 liter/hour to obtain a uniform coating of the fluoropolymer on the polycarbonate resin particles. The proportion of fluoropolymer added is from 0.01 to about 70 parts for each 100 parts by weight of polycarbonates and mixing is carried out to continually bring polycarbonate resin particles (non-contacted) into contact with the fluoropolymer dispension as it is added.
