Emulsion polymerization of ethylenically unsaturated monomers in hydroxy-terminated organic compounds

Abstract From the Canadian patent

Finely-divided dispersed solids are prepared by the emulsion polymerization in the presence of a free radical catalyst of a major amount of an ethylenically unsaturated monomer or mixture of monomers and a minor amount of a hydroxy-terminated organic compound having from one to eight hydroxyl groups a, hydroxyl equivalent weight of from 250 to 10,000 and an acid number of one or less and containing a polymerizable carbon-tocarbon double bond. The resulting polymeric solids are particularly useful in the preparation of reinforced polymer compositions.
