PCT No. PCT/FR94/01432 Sec. 371 Date Sep. 22, 1995 Sec. 102(e) Date Sep. 22, 1995 PCT Filed Dec. 8, 1994 PCT Pub. No. WO95/15991 PCT Pub. Date Jun. 15, 1995The invention relates to a process for the preparation of copolymers or polycondensates having solvating properties. The process for the preparation of a copolymer or a polycondensate comprised essentially of solvating units susceptible of inducing crystallinity, units reducing the crystallinity of the copolymer or of the polycondensate, and optionally cross-linkable units, all said units being of the oxyalkylene type or of the oxyalkenylene type, is characterized in that during a first step, a copolymer or a polycondensate is prepared, said copolymer or polycondensate comprising solvating units susceptible of inducing crystallinity and units which have a carbon/carbon insaturation in conditions which do not affect said insaturation and in that during a second step, at least a portion of the insaturations is subjected to hydrogenation. Application to the preparation of copolymers useful for producing ionic condition materials.
