Grafted block copolymers, process for their manufacture and use of these copolymers

摘要

A grafted block copolymer having a backbone and grafts produced by monomers, the backbone consisting of sequentially distributed units wherein at least one block of the backbone is soluble in the monomer composition from which the grafts are produced and in that at-least one block of the said backbone is insoluble in the said monomer composition and the process of making such grafted block copolymer by radical grafting and radical polymerization of a monomer on the backbone are preformed.
