Abstract
A method of producing partially crosslinked rubber-resin composition comprising directly feeding a pelletized peroxide-curable olefin copolymer composition, a peroxide-decomposing polyolefin resin and an organic peroxide compound to a twin-screw extruder under specific extruding conditions of weight of the copolymer rubber and specific energy at extrusion.
Claims5
A method of producing partially crosslinked rubber-resin composition comprising directly feeding a pelletized peroxide-curable olefin copolymer rubber and a peroxide-decomposing polyolefin resin together with an organic peroxide compound to a twin-screw extruder so that the rubber and the resin are subjected to a dynamic heat treatment in the presence of the peroxide under the following conditions:
- X.ltoreq.200, and
- Y.gtoreq.0.003X+0.12
- wherein "X" is the weight of the copolymer rubber (g/100 particle), and "Y" is the specific energy at the extrusion (KWhr/kg).
