Abstract
A study of the polymerization of styrene, methyl methacrylate, acrylonitrile, vinyl acetate and vinylidene chloride with various organic polysulfides as polymerization initiators has been made. Diphenyl, dibenzyl, dibenzoyl, dithiobenzoyl, dibenzothiazoyl, and dialkyl xanthogene disulfides are ineffective as initiators of thermal polymerization of these monomer at the temperature range from 60 to 120°C. The tetralkyl thiuram disulfides initiate the polymerization of styrene and methyl methacrylate, but in acrylonitrile, vinyl acetate and vinylidene chloride no polymerization occurs.
It was also found that all organic disulfides were excellent as photosensitizers for the photopolymerization of these monomers.
Die Polymerisation von Styrol, Methylmethacrylat, Acrylnitril, Vinylacetat und vinylidenchlorid in Gegenwart verschiedener organischer Polysulfide wurde untersucht. Diphenyl-, Dibenzyl-, Dibenzoyl-, Dithiobenzoyl-, Dibenzothiazoyl- und Dialkylxanthogen-Disulfide sind als Initiatoren der thermischen Polymerisation (bei 60–120°C) wirkungslos. Tetralkylthiuram-Disulfide initieren nur die Polymerisation von Styrol und Methylmethacrylat, aber nicht die Polymerisation von Acrylnitril, Vinylacetat und Vinylidenchlorid.
Es wurde gefunden, daß alle organischen Disulfide sehr gute Photosensibilisatoren für die Photopolymerisation der oben angegebenen Monomeren sind.
