Title (EN) SYNDIOTACTIC COPOLYMERS OF PROPYLENE AND OLEFINS
(FR) COPOLYMERES SYNDIOTACTIQUES DE PROPYLENE ET D'OLEFINES
Abstract:
(EN) Copolymers of propylene and olefins having from 2 to 10 carbon atoms in which the microstructure of the side chain is highly syndiotactic, more particularly random copolymers. Also disclosed is a process for preparing said copolymers by metallocene catalysis using an asymmetric bridged dicyclopentadienyl derivative of a metal of groups 4b, 5b or 6b.
(FR) Des copolymères de propylène et d'oléfines possédant entre 2 et 10 atomes de carbone, dans lesquels la chaîne latérale possède une microstructure hautement syndiotactique, plus spécialement les copolymères désordonnés. On décrit également un procédé de préparation desdits copolymères 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.
