Abstract: PURPOSE:To obtain a high ionic conductivity and excellent mechanical properties by hardening a compsn. comprising an acryloyl-modified polyalkylene oxide, a polyalkylene glycol-polyvinyl chloride block copolymer, and an inorg. ionic salt. CONSTITUTION:The title solid electrolyte is prepd. by hardening a compsn. comprising an acryloyl-modified polyalkylene oxide, a block copolymer contg. a polyalkylene glycol and a polyvinyl chloride, and an inorg. ionic salt. The acryloyl-modified polyalkylene oxide pref. has a mol.wt. of about 250-3000. The addition of a polyalkylene glycol of the general formula, R'O-(CH2CHRO)n- R'' (wherein R, R', and R'' are each H or lower alkyl; and (n) is an integer of 3-30), or a deriv. thereof as the fourth component to the compsn. can further enhance the ionic conductivity.

Abstract: PURPOSE:To improve water resistance and to prevent the deterioration and change in properties of a liquid crystal and a dichroic dye by impregnating the liquid crystal or the liquid crystal and the dichroic dye into the communicating gap parts in a porous film of a three-dimensionally crosslinked structure and thereby forming the combined film. CONSTITUTION:This film is formed by emulsifying and crosslinking a mixture composed of an aq. water soluble polymer soln. and excess polyisocyanate or a mixture composed of an aq. water soluble polymer soln., the polyisocyanate and a high boiling compd., then removing the unreacted polyisocyanate or the high boiling compd. and impregnating the liquid crystal into the resulted water resistant porous film. The water soluble polymer is exemplified by polyvinyl alcohol and polypropylene glycol, the polyisocyanate by diisocyanate and triisocyanate and the high boiling compd. by, for example, liquid paraffin, octyl benzene, etc., which hardly evaporate at the time of crosslinking. The water resistance is improved in this way and the deterioration of the liquid crystal and the dichroic dye is prevented.
