Since the solvent-free polymer electrolyte contains no liquid organic electrolyte, it is not accompanied by problems caused by leakage or evaporation of an organic solvent, unlike a gel-type polymer electrolyte. Furthermore, the solvent-free polymer electrolyte has enhanced ionic conductivity as compared to a conventional solvent-free polymer electrolyte.

摘要： A hyperbranched polyetherketone and a heat-resistant blend of polyvinylchloride with the same. The polyetherketone is synthesized by self-polycondensation of 3,5-bis[4-[(2,3,4,5,6-pentafluorophenyl)carbonyl]phenoxy]-4-hydroxybenzophenone or 3,5-difluoro-4-hydroxybenzophenone, and then substituting 50 to 80 mole % of fluorine atoms present in the side chains and ends of the PEK molecule by polar groups. In addition, a blend of polyvinylchloride can be manufactured using the hyperbranched polyetherketone by a melt blending technique applicable for industrial purpose at a temperature of 180 to 120° C., and thus the blend of polyvinylchloride with the polyetherketone can be applied to high temperature end-use products such as hot water pipes.

摘要： The present invention discloses aliphatic polyester compound having highly branched structure for polyvinylchloride plasticizer and polyvinylchloride blend containing the same. Aliphatic polyester compound having highly branched structure for polyvinylchloride plasticizer according to the present invention is formed by self-condensation polymerization of monomer having one carboxy functional group and two hydroxy functional groups. Since such aliphatic polyester having highly branched structure has superior compatibility with polyvinylchloride and never flows out contrary to the conventional liquid plasticizer having low molecular weight of phthalate, etc., the problems such as the disturbance of endocrine system of human body and the destruction of ecosystem due to the efflux of plasticizer is not caused and since the same has superior efficiency of plasticization, it is possible to give polyvinylchloride sufficient flexibility.
