Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
80 words
A method of producing a conductive anisotropic polymer material comprising 20-50 weight parts of conductive black and 100 weight parts of the reaction product of perchlorovinyl resin and phenylaminomethyl-methyldiethoxysilane, comprising the steps of dissolving 100 weight parts of perchlorovinyl resin in 40-80 weight parts of dichloroethane; adding successively 10-100 weight parts of phenylaminomethyl-methyldiethoxysilane and 40-100 weight parts of conductive black to the resulting solution; stirring the mixture thus obtained, and rolling it at a temperature of 15° to 50° C.
Claim 2
Independent Claim
80 words
A method of producing a conductive anisotropic polymer material comprising 20-50 weight parts of conductive black and 100 weight parts of the reaction product of perchlorovinyl resin and phenylaminomethyl-methyldiethoxysilane, comprising the steps of dissolving 100 weight parts of perchlorovinyl resin in 40-80 weight parts of dichloroethane; adding successively 10-100 weight parts of phenylaminomethyl-methyldiethoxysilane and 40-100 weight parts of conductive black to the resulting solution; stirring the mixture thus obtained, and rolling it at a temperature of 15° to 50° C.
Claim 3
Dependent Claim
32 words
A conductive anisotropic polymer material comprising 20-50 weight parts of conductive black and 100 weight parts of a mixture of perchlorovinyl resin and phenylaminomethyl-methyldiethoxysilane and prepared by the method of claim 1.
