23443-373 Disclosed is a process for bonding a thermoplastic polyphenylene ether (PPE) containing polymer and a rubber by covulcanization, the process comprising the steps of heating and covulcanizing the PPE-containing polymer and the rubber. The rubber comprises: (a) 100 parts by weight of a rubber component comprising 100-20 wt.% of an EP(D)M rubber and 0.80 wt.% of a styrene-butadiene rubber obtained by emulsion polymerization, (b) 100-300 parts by weight of loading material, (c) 1-10 parts by weight of a peroxide vulcanization agent, and (d) 0.5-4 parts by weight of a vulcanization activator. The PPE-containing polymer may contain, in addition to the polyphenylene ether, up to 20 parts by weight (per 100 parts of PPE) of polyalkenylene and/or up to 100 parts by weight (per 100 parts of PPE) of a styrene polymer. The PPE-containing polymer and the rubber can be permanently bonded. The product can take various shapes, such as boards, tubes, and so on. |
