| Abstract: | The reactive melt blending of polymethylmethacrylate (PMMA) and polycarbonate (PC) in the presence of various catalysts was studied. The effects of different kinds of catalysts on chemical reaction between PMMA and PC during melt blending were investigated. According to the results of IR analysis, changes in equilibrium torque, and transparency observation of blends, lithium acetate, magnesium acetate, sodium silicate, manganese acetate, polyphosphoric acid, dibutyltin oxide, and dibutyltindilaurae were found to be effective to catalyze the interfacial reaction between PMMA and PC. The PMMA/PC grafted copolymers produced in situ as compatibilizers could improve the compatibility of PMMA/PC blends and lead to semitransparent blends. Lanthanum chloride, nickel acetate, samarium chloride, hexane diacid, aluminum chloride, and sodium bromide were found to be not effective to catalyze the reaction between PMMA and PC. |
