US 2013/0253146 A1 · DIELECTRIC POLYMERS WITH ELEVATED PERMITTIVITY, PROCESS FOR PREPARATION THEREOF AND END USES THEREOF

Abstract

The present invention relates to a polymer which has an electronic dipole covalently bonded to the polymer structure. The polymer structure forming the basis of the polymer is in particular an elastomer which can be unbranched, or also branched or crosslinked. The present invention equally describes a method for bonding a dipole molecule to a corresponding polymer structure or elastomer structure. The polymer in accordance with the invention can be present as a pure substance or also as a mixture with any other polymers, preferably with further elastomers. Uses of the polymer or of the obtained polymer blend will equally be provided.

where
A is an electron acceptor functionality selected from —NO2, —CN, —F, —CF3, cyanovinyl-, dicyanovinyl- or tricyanovinyl-residues;
X is an organic residue with a delocalized electron system which allows a delocalization of the electrons between D and A;
D is an electron donor functionality selected from —O— or —N(B)—, where B is hydrogen or a linear or branched alkyl residue with 1 to 16 carbon atoms;
R represents an alkylene residue with 1 to 16 carbon atoms;
n=0 or 1 and
m=1, 2, 3 or 4.
