Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
61 words
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.
Claim 2
Dependent Claim
61 words
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.
Claim 3
Dependent Claim
21 words
The epoxy resin composition according to claim 1, wherein a part of said polymer is chemically bonded to said epoxy resin.
Claim 4
Dependent Claim
24 words
