Abstract

Patente de Invenção: <B>"CONTROLE DA MORFOLOGIA EM COPOLìMEROS DE ENXERTO DE POLIPROPILENO"<D>. Um copolímero de enxerto compreendeno uma parte principal de um material de polímero de propileno tendo um enxerto de monómero de vinila polimerizado no mesmo é produzido por meio de: (1) tratamento do material de polímero de propileno com um iniciador de polimerização de radical livre; (2) t ratamento do material de polímero de propileno com pelo menos um monómero de enxertagem capaz de ser polimerizado pelos radicais livres na presença de um modificador da taxa de polimerização, e (3) remoção de qualquer monómero de enxertagem não-reagido do material de polímero de propileno co-polimerizado de enxertagem, decomposição de qualquer iniciador não-reagido e desativação de quaisquer radicais livres residuais no material. O uso do modificador da taxa de polimerização aumenta o tempo de indução de polimerização sobre a superfície do polímero, conseq³entemente, facilitando a difusão do monómero no interior das partículas de polímerode modo que a polimerização da superfície do monómero seja iniciada.
