| titleOfInvention | Dipol-modified polyurethane, method for obtaining it and use in the production of electro-active polyurethane-based cast elastomer films |
| abstract | The present invention relates to a process for producing a polyurethane dielectric polymer comprising the steps: (a) Preparation of a dipole-functionalized polyisocyanate by reacting a polyisocyanate having an NCO functionality of> 2.0 with a dipole compound of the general formula (I) (Z) - (R) n - (D) -X- (A) m (Formula I) in the Z is a functional group having at least one Zerewitinoff-active hydrogen atom, X is an organic radical with a delocalized electron system, A is an electron acceptor functionality selected from the group consisting of -NO 2, -CN, -F, -Cl, -CF 3, -OCF 3, cyanovinyl, dicyanovinyl, or tricyanovinyl radicals; D is an electron donor functionality selected from the group consisting of -O-, -S- or -N (B) -, wherein B is hydrogen or a linear or branched alkyl radical having 1 to 16 carbon atoms, R represents an alkylene radical having 1 to 16 carbon atoms, wherein n = 0 or 1 and m = 1, 2, 3 or 4; (B) subsequent reaction of the obtained after step (a) dipole-functionalized polyisocyanate with (aa) a polyisocyanate component and (bb) a polyol component. n n n The invention further relates to a produced by the process dielectric polyurethane polymer and its use. |
