Title (EN) SYNDIOTACTIC HOMOPOLYMERS OF OLEFINS
(FR) HOMOPOLYMERES SYNDIOTACTIQUES D'OLEFINES
Abstract:
(EN) Homopolymers of olefins having from 4 to 10 carbon atoms in which the microstructure of the polymer chain consists of blocks of repeating racemic dyads predominantly connected by units consisting of a meso triads. Also disclosed is a process for preparing said homopolymers by metallocene catalysis using an asymmetric bridged dicyclopentadienyl derivative of a metal of groups 4b, 5b or 6b.
(FR) Des homopolymères d'oléfines possédant entre 4 et 10 atomes de carbone, dans lesquels la chaîne polymérique possède une microstructure constituée de blocs de radicaux bivalents racémiques et répétiteurs reliés de manière prédominante par des unités constituées de méso-atomes trivalents. On décrit également un procédé de préparation desdits homopolymères par la catalyse à alliage organométallique au moyen d'un dérivé de dicyclopentadiényle asymétrique et à pont d'un métal des groupes 4b, 5b ou 6b.
