Title (EN) SELECTIVE CATALYTIC PROCESS FOR PREPARING N-HALOTHIOSULFONAMIDE MODIFIED POLYOLEFINS
(FR) PROCEDE CATALYTIQUE SELECTIF DE PREPARATION DE POLYOLEFINES MODIFIEES PAR UN N-HALOTHIOSULFONAMIDE
Abstract:
(EN) A process is provided for preparing an 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 an 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.
(FR) Procédé de préparation d'une polyoléfine modifiée par un N-halothiosulfonamide d'au moins un 1-alcène, et d'au moins un diène, lesquels après incorporation dans la polyoléfine comprennent un atome de carbone entièrement substitué, par exemple 5-éthylidène-2-norbornène. Le procédé consiste à faire réagir un N-halothiosulfonamide avec la polyoléfine en présence d'une base non nucléophile et d'un catalyseur comprenant un sel d'un acide faible de métaux spécifiés. Le procédé est particulièrement adapté pour être mis en ÷uvre dans la phase de fusion.
