Abstract

NANOCOMPóSITO EM POLIPROPILENO BASEADO EM UM COMPATIBILIZANTE Descreve-se um nanocompósito em polipropileno baseado em um novo compatibilizante. Um novo compatibilizante é obtido através da reação química entre um aminoalquilsilano e um palipropileno enxertado com anidrido maleico (PP-g-AM) via extrusão reativa. Após a etapa de extrusão, peletização e secagem, o novo compatibilizante é adicionado durante a incorporação de uma argila organofílica ao polipropileno em extrusora de rosca dupla. O nanocompósito obtido por este método apresenta propriedades mecânicas, térmicas e óticas superiores àqueles empregando compatibilizantes baseados em polipropileno enxertado com anidrido maleico.A POLYPROPYLENE NANOCOMPOSITE BASED ON A COMPATIBILIZER A polypropylene nanocomposite based on a new compatibilizer is described. A new compatibilizer is obtained by the chemical reaction between an aminoalkylsilane and a maleic anhydride grafted palipropylene (PP-g-AM) via reactive extrusion. After the extrusion, pelletizing and drying step, the new compatibilizer is added during the incorporation of an organophilic clay into the polypropylene in twin screw extruder. The nanocomposite obtained by this method has superior mechanical, thermal and optical properties than those employing compatibilizers based on maleic anhydride grafted polypropylene.
