ABSTRACT:
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.
