PURPOSE: To produce an article consisting of members firmly bonded to one another by blending a compound of a vulcanizable rubber and a polyamide composition with a specified silane and vulcanizing the rubber with a peroxide.
CONSTITUTION: A polyamide matrix containing at most 30 wt.% thermoplastic resin or polyamide and a rubber compound containing 100 pts.wt. rubber, fillers, a plasticizer, 1-10 pts.wt. peroxide vulcanization agent, vulcanization activators and 1-10 pts.wt. silane of the formula (wherein R1 is a divalent group or a direct bond; R2 is H, a 1-20C alkyl, or the like; and R3, R4 and R5 are each the same as R2 or -COOR2) are vulcanized. The polyamide component used comprises a polyamide, a polyamide molding material, a polyamide blend, or a fibrous composite material having a polyamide matrix. The silane is used in an amount of 2-6 pts.wt. based on 100 pts.wt. rubber. The silane used comprises, e.g. vinyltrimethoxysilane or vinyl-tris(2-methoxyethoxy) silane. The rubber used comprises, e.g. an ER(D)M-rubber, E-SBR, L-SBR, BR or NR. A vulcanization retarder, an age resistor, etc., may be blended.
