Abstract
A copolymer of the present invention is produced by copolymerization of an electron-donating monomer having an electron-accepting group and an electron-accepting monomer having an electron-accepting group. The copolymer thus exhibits a high dielectric constant, a low level of hygroscopicity and good adhesion.
Claims14
A binary copolymer produced by free radical polymerization of a vinyl ether monomer having a first electron-accepting group and an acrylate monomer having a second electron group wherein
- one of said first and second electron-accepting groups is selected from the group consisting of cyanoalkyl and cyanoalkyloxyalkyl groups,
- while the other of said first and second electron-accepting groups is selected form the group consisting of cyanoalkyl, cyanoalkyloxyalkyl and haloalkyl groups.
