Abstract
O presente trabalho teve por objetivo avaliar as propriedades mecânicas, térmicas e morfológicas de sistemas à base de poliolefinas (PP e HDPE) e copolímero metalocênico de etileno/1-octeno (EOC), produzido pela Dow Chemical. Foi também investigada a atuação de um copolímero metalocênico de propileno/1-octeno (POC), sintetizado em laboratório, como agente compatibilizante da mistura PP/EOC. Os resultados mostraram que a adição de teores específicos de EOC ao HDPE e PP pode levar à produção de materiais com boas propriedades mecânicas. Os dados obtidos também revelaram que o copolímero POC pode ser usado como agente compatibilizante das misturas PP/EOC.
The aim of this work was to evaluate the mechanical, thermal and morphological properties of systems based on polyolefins (PP and HDPE) and ethylene/1-octene metallocene copolymer (EOC), produced by Dow Chemical. The effect of a propylene/1-octene metallocene copolymer (POC), obtained in the laboratory was also investigated as a compatibilizer agent for the PP/EOC blend. The results showed that the addition of certain contents of EOC to PP and HDPE may carry the production of materials with good mechanical properties. The data obtained also revealed that the POC copolymer can be used as compatibilizer agent of the PP/EOC blends.
