    摘要: Resin compositions of improved dispersibility and mechanical properties are obtained by polymerizing a polymerizable compound (A), insitu in a melted thermoplastic resin (B), in the presence of a dispersant (C) reactive or compatible with at least one of the resin (B) and polymerizate of (A).Suitable dispersants include those represented by the general formula (1) or (2)R.sub.1 --L(X--M--X--L).sub.n X--M--R.sub.2 (1)R.sub.1 --L(X--M--X--L).sub.n --R.sub.2 (2)wherein R.sub.1 and R.sub.2 are groups, such as hydrocarbyl acyl, alkoxy, hydroxyl, mercapto, amino, epoxy, isocyanate, carboxylic, carboxylic anhydride, carboxylic halide and aldehyde groups; L and M are residues of a polymer having a number average molecular weight of about 500-about 3,000,000, the difference in solubility parameter between the residue L or M and the resin (B) or polymerizate of (A) being not more than 0.5; X is a residue of a difunctional compound, such as organic diisocyanates, dicarboxylic acids, diamines, diols and diepoxides, the molecular weight of X being not more than a quater of that of L and M; and n is 0 or an integer of at least 1.
