  • Process for the polymerisation of vinyl-containing monomers
    Publication number: 20090118444
    Abstract: The invention relates to a process for the polymerisation of monomeric vinyl halides in a polymerisation reactor, especially using a reflux condenser, and also to a polymerisation reactor for carrying out the process according to the invention. As a result, the space-time yield (STY) of an exothermal reaction can be substantially improved whilst the product quality remains almost the same.
