Abstract

An epoxy resin composition comprising an epoxy resin and a polyfluoroalkyl group-containing polymer uniformly dispersed therein, said polymer having been formed by polymerizing a polyfluoroalkyl group-containing polymerizable compound in said epoxy resin.

Claims

1. An epoxy resin composition, comprising an epoxy resin and a polyfluoroalkyl group-containing polymer uniformly dispersed therein, wherein said polymer is obtained by polymerizing a polyfluoroalkyl group-containing polymerizable compound in said epoxy resin;

wherein said polyfluoroalkyl group contains a perfluoroalkyl group having from 3 to 21 carbon atoms at its terminal, and wherein said polymerizable compound is a polyfluoroalkyl group-containing unsaturated ester.

2. The epoxy resin composition according to claim 1, wherein a part of said polymer is chemically bonded to said epoxy resin.

3. The epoxy resin composition according to claim 2, wherein the epoxy resin has a functional group capable of being chemically bonded to said polymer.

4. The epoxy resin composition according to claim 1, wherein said polymer has a particle size of from 0.01 to 100 μ

m.

5. The epoxy resin composition according to claim 1, wherein the weight ratio of the epoxy resin to the polymer is within a range of from 40:

60 to 99;

1.

6. The epoxy resin composition of claim 1, wherein said polyfluoroalkyl group-containing unsaturated ester contains, as atoms or groups, only carbon atoms, hydrogen atoms, fluorine atoms, chlorine atoms, nitrogen atoms, and SO₂ groups.

7. The epoxy resin composition of claim 1, wherein said unsaturated ester is at least one member selected from the group consisting of ##STR2##
