Zusammenfassung:	PURPOSE:To efficiently injection-mold product, which had favorable external appearance, is excellent in mechanical strength such as tensile strength, wear resistance, flexural resistance or the like and has small permanent compressive strain. CONSTITUTION:Rubber composition is prepared by adding 1-7 pts.wt. of reactive silyl group-containing 1,3-diene polymer, crosslinker and other normal compounding chemicals to 100 pts.wt. of diene-based rubber. The resultant rubber composition is injected at 90-130 deg.C so as to be changed in a mold cavity and finally heated up to 130-190 deg.C for crosslinking.
