In order to provide a crosslinking formed body having a low hardness and superior tensile characteristics and rubber properties, an ethylene-.alpha. olefin copolymer, polypropylene, and an organosilane compound are graft polymerized in the presence of a free radical generating agent to form a reaction product, the reaction product is formed into a desired shape formed body, and the formed body is crosslinked by being exposed to moisture in the presence of a silanol catalyst.

Method of manufacturing a crosslinking formed body

An optical part for light transmission comprises a light conductor formed of a core of a transparent material and a clad of a material having a smaller refractive index than that of the core material, and a light emitting and/or receiving element, wherein the light emitting and/or receiving element is integrally combined with the core of the light conductor by a same material as the core material or by a material having a same refractive index as that of the core material and having a greater rigidity than that of the material forming the clad and/or jacket. The optical part can be used in a high temperature environment as well as a room temperature environment without involving any appreciable loss in light transmission.

Optical part including integral combination of optical fiber and light

A semiconductive resin composition comprising 100 parts by weight of a polymer component comprising an ethylene-based copolymer, an ethylene-propylene rubber, and a low molecular weight polyethylene having an average molecular weight of 1,000 to 4,000 and 40 parts by weight or more of electroconductive carbon black.

Semiconductor resin composition

A synthetic resin optical fiber having the structure simplified and a stable light transmission characteristic is disclosed. The synthetic resin optical fiber comprises a transparent core and a cladding formed around the core, and the cladding has an inner transparent portion and an outer peripheral portion containing a light interruption substance such as a pigment and the like.
