POLYMERES SEQUENCES GREFFES CONTENANT AU MOINS UNE SEQUENCE POLYOLEFINIQUE OU POLYDIENIQUE COMPORTANT UN CYCLE SUCCINIMIDE SUBSTITUE SUR L'AZOTE PAR UN GROUPEMENT REACTIF

摘要

The invention concerns grafted block polymers containing at least one polyolefin or polydiene sequence comprising at least one succinimide cycle substituted on nitrogen by a reactive group of formula -R(-X)n wherein: -X represents a reactive group, n is a number not less than 1 and -R is a radical comprising at least one carbon atom, and containing at least one sequence of varied type, different from polyolefin or polydiene type, the methods for preparing them and their uses. The invention also concerns polymer mixtures comprising at least two polymers different from each other whereof one at least is a grafted block polymer as defined above and their uses.
