Abstract
A method of producing a heat-resistant chlorine-containing crosslinked resin formed body, formed from: Step (a) of melt-mixing, to a base resin containing a chlorinated polyethylene and a polyvinyl chloride and a plasticizer, an organic peroxide, an inorganic filler, and a silane coupling agent, at a specific ratio, at a temperature equal to or higher than a decomposition temperature of the organic peroxide; Step (b) of mixing a silane masterbatch obtained in Step (a) and a silanol condensation catalyst; and Step (c) of crosslinking by bringing a formed body obtained by Step (b) into contact with water; wherein, in Step (a), from 5 to 55 mass % of the plasticizer is contained in 100 mass % of the base resin to be used in the reaction with the silane coupling agent; the formed body produced therefrom; a silane masterbatch and a mixture thereof; and a heat resistant product.
