Title
(EN) MANUFACTURE OF STEREOREGULAR POLYMERS
(FR) FABRICATION DE POLYMERES STEREOREGULIERS
Abstract
(EN)
The present invention teaches the use of particular soluble metallocene catalysts to produce stereoregular polymers in gas phase polymerizations wherein the catalysts are fed into a particle lean zone in the reactor. The metallocenes catalysts are bridged bis-(substituted indenyl) compounds.
(FR)
Utilisation de catalyseurs à base de métallocène solubles particuliers pour produire des polymères stéréoréguliers par polymérisation en phase gazeuse, au cours de laquelle les catalyseurs sont introduits dans une zone pauvre en particules dans le réacteur. Les catalyseurs à base de métallocène sont des composés de bis-(indényle substitué) pontés.
