An ultraviolet-crosslinkable polymer composition comprising a polymer containing iodine and/or bromine in an amount of from 0.001 to 10% by weight, a photoinitiator as a crosslinking agent and a polyfunctional unsaturated compound as a crosslinking aid. By using iodine and/or bromine as a crosslinking point, it is possible to carry out crosslinking of various polymers including fluorine-containing polymers which have been very difficult to crosslink with ultraviolet rays, and molding or processing can be made easily at working site at low temperature.

Polymer composition crosslinkable with ultraviolet

A transparent elastomer composition is obtained by co-coagulation of an emulsion of fluorine-containing resin fine particles having an average particle size of from 20 to 150 nm and an emulsion of elastomer particles, in which the fluorine-containing resin fine particles are finely dispersed uniformly in the elastomer. The transparent elastomer composition provides an elastomeric molded article having excellent mechanical strength, abrasion resistance and transparency.
