    摘要: Method for the production of a thermostable crosslinked PVC copolymer where the crosslinking is carried out in the presence of humidity and after processing of the polymer. The copolymer is a copolymer of vinyl chloride and 0.05-10 weight % of a vinyl containing alkoxysilane compound. Preferably methacryloxy-propyltrimethoxy-silane or methacryloxy-propyltriethoxysilane is used as comonomer. The crosslinking can be carried out independent of the type of stabilizer. A condensation catalyst and also an inhibitor can be used to prevent too early crosslinking.
