Copolymers based on grafted olefins and method for obtaining same

摘要

Olefin-based copolymers made affine by grafting, characterised in that they are composed of: i) at least one polyolefin functionalised with reactive functions of an appropriate type and in controlled number; ii) and at least one mono-functional type oligomer with a predetermined chain length, a low polydispersity index and an absolutly controlled structure, which is grafted on the functionalised polyolefin by means of reactive functions. These copolymers made affine by grafting are designed to be placed in intimate contact with materials of non-olefinic or olefinic composition with which the copolymers were not initially compatible.
