Claim 1
Independent Claim
130 words
THE POLYMERIZATION AS A SEPARATE MONOMER PHASE OF AN UNSATURATED MONOMER CONTAINING A SINGLE METHYLENE GROUP ATTACHED TO A CARBON ATOM BY A DOUBLE BOND AND POLYMERIZABLE BY PEROXY COMPOUND WHICH COMPRISES INITIATING THE POLYMERIZATION OF THE MONOMER AS A SEPARATE MONOMER PHASE IN AN ALKALINE WATER PHASE BY MEANS OF AN ORGANIC PEROXYDICARBONATE FORMED IN THE PRESENCE OF THE MONOMR BY REACTING AN ALKYL HALOFORMATE PRESENT IN THE MOOMER PHASE WITH A PEROXIDE PRESENT IN THE WATER PHASE WHILE MAINTAINING THE TEMPERATURE OF THE DISPERSION AT A VALUE SUFFICIENT TO BRING ABOUT THE REACTION BUT BELOW ABOUT 60*C. THE HALOFORMATE IN THE MONOMER PHASE BEING PRESENT IN AMOUNT FROM ABOUT 0.00K TO ABOUT 1.0 PART PER 100 PARTS OF MONOMER AND SUFFICIENT PEROXIDE PRESENT TO REACT WITH THE HALOFORMATE.
