Abstract

PURPOSE:To stabilize the extrusion rate of an organic polymer, and to obtain a high precision crosslinked organic polymer molded article, by supplying an extruder with a resin composition obtained by the room-temperature mixing of powdery resin having specific surface area and a liquid compound such as silyl-modifiable silane. CONSTITUTION:A resin having a specific surface area of 10<4>cm<2>/1l, a silane compound, and a radical generator, and if necessary, a siloxane-condensation catalyst filter, are throughly mixed together by a V-blender at room teperature. The mixture is charged in a hopper 2 of an extruder 1, and melt-extruded to form a uniform ex trudate. The amount of the liquid such as silane is <=5wt% based on the resin. By keeping the ratio of the surface ara of the resin to the volume of the silane compound as high as the range given above, the slipping between the inner surface of the extruder cylinder and the resin can be minimized, and stable extrusion is attained.
