    • The application discloses a functionalized multiblock macromonomer of formula: ##STR1## or of formula: ##STR2## in which formulae: each of the blocks A, B and C represents a sequence of a monomer chosen from the acrylic, vinylaromatic, methacrylic, diene, vinylpyridine, vinylpyrrolidone, alkylene oxide, lactam, lactone and maleimide monomer classes, on condition that at least one of the blocks A and C is chosen from a different class to that of block B and that at least one of the blocks A, B or C is a (meth)acrylic sequence,m, n and p are integers representing the number of monomer units in the sequence under consideration, such that 3.ltoreq.n.ltoreq.1000, 0.ltoreq.m.ltoreq.1000 and 0.ltoreq.p.ltoreq.1000, on condition that m and p are not 0 at the same time, andF is a group terminated by O.sup.-, by OH, by an .alpha.,.beta.-ethylenic unsaturation, or by an oxirane groups.Also disclosed are processes for preparing the functionalized multiblock macromonomer which macromonomer combines the advantages of multiblock polymers containing acrylic sequences with the reactivity of macromonomers.
