MONO-OLEFIN POLYMERS HAVING METHYLOL PHENOLIC GROUPS GRAFTED THERETO, A PROCESS FOR THEIR PRODUCTION AND POLYMER BLENDS CONTAINING THEM

摘要

Mono-olefin polymers having methylol phenolic groups grafted thereto are prepared by reacting a mon-olefin polymer with a methylol phenolic material in the presence of an activator such as a Lewis acid. The grafted polymers can be used as components of blends with other polymers having an affinity for methylol phenolic groups or as compatibilizers in blends of polyolefins with other polymers such as polyamides or polyesters which are normally incompatible or only partially compatible with polyolefins.
