Abstract

"CATALISADOR APERFEIçOADO PARA HOMO- E CO-POLIMERIZAçãO DE OLEFINA". A presente invenção refere-se a um catalisador de titânio complexo sólido para homopolimerização e copolimerização de <244>-olefina, obtido através de: (i) produção de uma solução de um composto de magnésio através da dissolução de um composto de magnésio e um composto do Grupo IIIA da Tabela Periódica em um solvente misturado com éter cíclico, um ou mais tipos de álcool, um composto fosforoso e um organossilano; (ii) precipitação das partículas sólidas através da reação da solução de magnésio com um composto de metal de transição, um composto de silício ou uma mistura deles, e (iii) reação das ditas partículas sólidas precipitadas com um composto de titânio e um doador de elétron. O catalisador da presente invenção é de tamanho de partícula grande, distribuição de partícula estreita e alta atividade catalítica, enquanto que os polímeros obtidos com o uso deste catalisador são de excelente estereorregularidade.
