Abstract
Graft stereoblock polymers are described which contain at least one polyolefin or polydiene type sequence comprising at least one succinimide ring substituted on the nitrogen atom by a reactive group with formula —R(—X)n, where —X represents a reactive group, n is a number greater than or equal to 1 and —R is a residue containing at least one carbon atom, and containing at least one sequence of a variety of natures, different from a polyolefin or polydiene. Their preparations and uses are also described. Mixtures of polymers comprising at least two polymers which are different from each other, at least one of which is a graft stereoblock polymer as defined above, and their uses, are also described.
