Novel polymer compsns. (I), for use as dispersant resins, are obtd. by reacting a hydroxylated polymer (II) with a polyfunctional isocyanate (III). The amt. of NCO gps. is 1.2-3.0 mol. per mol. of OH gps. of (II). Then the prod. (IV) is reacted with ammonia or a cpd. (V) having an isocyanate-reactive amino function. (II) is obtd. from 80-100 mol.% of a 1-25 C alkyl ester of an alpha , beta -unsatd. carboxylic acid, 0-20 mol.% of a comonomer, tetrahydrofuran hydroperoxide (THFHPO) as polymerisation initiator and opt. another polymerisation initiator and/or regulator, such that most of the chains of (II) are hydroxy-terminated. The process of prepn. of (I) is claimed, as well as (I) per se.
