Abstract

AbstractThe performance of the designed structured core‐shell latex particles in toughening polycarbonate (PC) matrix was examined. Izod impact testing of the PC‐core‐shell latex blends were used to evaluate the influence of parameters related to the core‐shell latex particles on toughening polycarbonate. Among these parameters are the particle size and levels of crosslinking of the core rubber particles, composition and molecular weight of the shell polymer, and weight ratio of shell to core polymers as well as the particle morphology. In this work, core‐shell structured latex particles with thinner shells of higher molecular weight polymers were found to improve the impact resistance of polycarbonate. The role of chain entanglements in increased adhesion between the discrete rubbery phase and the continuous glassy matrix and the importance of surface‐to‐surface interparticle distance for toughening at various temperatures are discussed. © 1995 John Wiley & Sons, Inc.
