Title:
SELECTIVE CATALYTIC PROCESS FOR PREPARING N-HALOTHIOSULFONAMIDE MODIFIED POLYOLEFINS
Document Type and Number:
WIPO Patent Application WO1991009064
Kind Code:
A3
Abstract:
A process is provided for preparing a N-halothiosulfonamide modified polyolefin of at least one 1-alkene, and at least one diene which, after incorporation in the polyolefin includes a carbon atom which is fully substituted, for example, 5-ethylidene-2-norbornene. The process comprises reacting a N-halothiosulfonamide with the polyolefin in the presence of a non-nucleophilic base and a catalyst comprising a salt of a weak acid of specified metals. The process is particularly suited to be performed in the melt phase.
