摘要： Solid organic polymers are chlorinated with chlorine to give chlorinated polymers in the presence of a solvent which contains from 20 to 100% by weight of phosgene and in which the polymer is dissolved or suspended, at or below the boiling point of the mixture of chlorine and solvent, by initiating the reaction with actinic light or another initiator which produces free radicals. A mixture of not less than 50% by weight of phosgene and a chlorofluorocarbon or chlorofluorohydrocarbon, such as chlorotrifluoromethane, can also be used as the solvent, but phosgene is most suitable.

摘要： In the hydrogenation of polymers or copolymers synthesized from dienes, or containing diene hydrocarbons, which is as a rule carried out in an organic solvent using hydrogen in the presence of conventional complex hydrogenation catalysts based on metals of sub-group 8 of the periodic table of the elements and aluminum trialkyls it is important to have from 0.5 to 50 moles of water present in the hydrogenation zone per mole of the heavy metal component of the catalyst. The hydrogenation time can be substantially reduced by this measure.
