PROCESS FOR THE PREPARATION OF A-SUBSTITUTED B-PROPIOLACTONE GRAFTED POLYMERS ON AMORPHOUS SUPPORTED POLYMERS

摘要

P Process for the preparation of grafted polymers of beta -propiolactones alpha -substituted on amorphous support polymers. The present invention relates to the preparation of grafted polymers of beta -propiolactones alpha -substituted comprising the stage of the creation of anionic sites in an amorphous support polymer and the reaction of the anionic compound formed with a beta -propiolactone alpha -substituted. The critical unsaturation concentrations in the support polymer and the critical amounts of the beta -propiolactone concerned are also indicated. Use of this process for grafting on weakly unsaturated substrates. /P
