摘要： Water-soluble films suitable for water-dissolvable packaging comprising a polyurethane polymer having defined amounts of poly(ethylene oxide) (and optionally poly(propylene oxide)) groups and acid (preferably carboxyl) groups at least 50% neutralised with a base, at least a proportion of which is of the non-volatile type, the polyurethane being made by chain extension of a urethane prepolymer. Also water-soluble packaging (sachets, capsules, bags) made from the films and their use in packaging various materials, and a process for the production of aqueous polyurethane solutions which may be used for making such films.

摘要： An electrochemical or an electroyltic device comprises a conductive anode and cathode separated by a solid electrolyte, and wherein one electrode surrounds the other, and the solid electrolyte comprises:(a) a matrix of polymer main chains, having side-chains linked to the main chains, which side chains comprise polar groups free from active hydrogen atoms,(b) a polar aprotic liquid dispersed in the matrix, and(c) an ionised ammonium, alkali metal or alkaline earth metal salt dissolved in the matrix and/or liquid, and a process for the preparation thereof.
