Abstract

The present invention relates to a process for preparing solutions of hydrogenated nitrile-diene copolymer, wherein the nitrile-diene copolymer dissolved in an ether-containing or ketone-containing solvent mixture is subjected to hydrogenation conditions. The invention further relates to solutions of hydrogenated nitrile-diene copolymer (HNBR solutions) comprising CPME as solvent, and to the use of HNBR solutions in CPME-containing solvent mixtures as binder in electrodes.
