    Abstract: Disclosed is a core-shell type polymer (A) having a rubbery core portion composed of a crosslinked vinylidene fluoride copolymer (a) wherein the vinylidene fluoride content is 30-90% by weight, and a shell portion composed of a vinylidene fluoride polymer (b) wherein the vinylidene fluoride content is more than that of the crosslinked vinylidene fluoride copolymer (a) and not less than 80% by weight. In this core-shell type polymer (A), the weight ratio (a)/(b) is from 30/70 to 90/10. This vinylidene fluoride based core-shell type polymer (A) is excellent in mechanical characteristics including flexibility and nonaqueous electrolyte solution resistance characteristics, and suitably used as a binder for nonaqueous electrochemical devices which enables, in combination with an active material powder, to form an electrode mix layer which exhibits excellent flexibility and excellent adhesion to an electrode collector.

    Abstract: PURPOSE: Provided are perfluorinated hydrocarbon polymers which can be used as fillers for the preparation of adhesive formulations having excellent dielectric properties, i.e., very low conductivity. This compositions display excellent rheological properties, in addition to low dielectric constants. The formulations can be used for a variety of purpose such as, for example, for the preparation of filled adhesive formulations with a reduced propensity to settle out, excellent dispensing characteristics due to the thixotropic nature thereof and the like. CONSTITUTION: The composition comprises a polymerizable monomer vehicle which, upon cross-linking, possesses good adhesion properties, wherein the vehicle is a maleimide, a (meth)acrylate, a propargyl ether material, an isomerized propargyl ether material, or a mixture of any two or more thereof; a perfluorinated hydrocarbon polymer having a particle size of 0.1-100 micrometer, a surface area of 0.2-20 g/m2 and a bulk density of at least 100 g/L; a curing catalyst.
