The invention relates to a binding agent comprising a mixture of a carboxylic acid vinyl ethylene ester copolymer (A) and a of olefin (B) containing a functional monomer (X), the mass ratio (B)/((A)+(B)) being between 0.05 and 1. Said binder has very good adhesion properties for adhering to a number of supports in photovoltaic modules, in addition to satisfactory transparency and electrical resistivity properties for the advantageous use of the binder in said modules.
A polyester resin composition having an improved molding processability and capable of providing molded articles having an improved impact resistance and other excellent properties such as mechanical strength and heat resistance, which comprises (a) a thermoplastic polyester, e.g. polyethylene terephthalate or a modified polyethylene terephthalate, (b) a polymer containing at least one epoxy group per molecule and having a modulus of elasticity of at most 10⁴ kg/cm², e.g. an α-olefin/glycidyl ester or ether copolymer, and (c) a copolymer of an α-olefin and an α,β-unsaturated carboxylic acid wherein at least 5 % by mole of the carboxyl groups are neutralized with an alkali metal.

A composition for solid polymer electrolyte which comprises a polyether polymer and an electrolyte salt compound soluble in the polyether polymer; wherein said polyether polymer is either (1) a polyether polymer having a toluene insoluble content of not larger than 5 weight %, or (2) a polyether polymer having a Mooney viscosity of 3 to 190, which has been prepared by applying a shearing force under heated conditions using an extruder to a polyether polymer having a Mooney viscosity of 10 to 200 so that the Mooney viscosity is reduced by 5 or more. This composition exhibits good film-forming property, and gives a solid polymer electrolyte exhibiting good and uniform ionic conductivity, and having high mechanical strength and surface smoothness. The solid polymer electrolyte is suitable for batteries and capacitors, especially for a lithium ion secondary battery.

A process for producing a polyether polymer by polymerizing a monomer having an oxirane group in the presence of a Lewis base having no active hydrogen such as, for example, a nitrile compound, a cyclic ether compound or an ester compound; and a polyether polymer produced by this process. Thus, a polyether polymer having a minimized amount of undesirable crosslinked product can be produced without reduction of polymerization activity.
