    • A polymer containing perfluoroalkyl group in its side chain which is an addition reaction product of a polymer having the following general formula: ##STR1## wherein R is phenyl group or alkoxyl group having 1 to 12 carbon atoms, R.sup.1 is alkyl group having 1 to 12 carbon atoms, and n is an integer of 10 to 2,000, with an epoxy compound selected from the group consisting of ##STR2## wherein R.sub.f is perfluoroalkyl group having 3 to 20 carbon atoms and R.sup.2 is alkyl group having 1 to 12 carbon atoms, the addition reaction product containing 0.1 to 50% by mole of the group derived from the epoxy compound having the formulae (IIa) to (IIc) per 1 mole of the recurring unit of the polymer having the formula (I). The polymer is good in compatibility with film-forming resins and solvents and improves the leveling property of a coating composition when incorporated thereinto and the surface smoothness of the film obtained from the composition.
    • 在其侧链中含有全氟烷基的聚合物,其是具有以下通式的聚合物的加成反应产物:其中R是苯基或具有1至12个碳原子的烷氧基,其中R1是具有 1〜12个碳原子,n为10〜2,000的整数,选自由下列组成的组的环氧化合物:(IIa)(IIb)和(IIc)其中Rf是全氟烷基 碳原子数为3〜20,R 2为碳原子数1〜12的烷基,加成反应产物相对于每1摩尔含有式(IIa)〜(IIc)的环氧化合物的基团为0.1〜50摩尔% 的具有式(I)的聚合物的重复单元。 该聚合物与成膜树脂和溶剂的相容性良好,并且当结合到涂料组合物中时改善涂料组合物的流平性和由组合物获得的膜的表面平滑度。
