Functionality polytopic block macro monomer and the production manner

摘要

A functionalized multisequenced macromonomer of formula (I) or formula (II), wherein each of blocks A, B and C represents a sequence of a monomer selected from the classes of acrylic, vinylaromatic, methacrylic, diene-containing, vinylpyridine, vinylpyrrolidone, alkylene oxide, lactam, lactone and maleimide monomers, with the proviso that either one or both of blocks A and C is selected from a class different from B, and that at least one of blocks A, B or C is a (meth)acrylic sequence; m, n, and p are integers representing the number of monomer structural units in the sequence in question, e.g.: 3 « n « 1000, 0 « m « 1000 and 0 « p « 1000, with the proviso that m and p are both 0 at the same time; and F is a grouping which terminated by 0-, OH or an α,β-ethylene unsaturation.
