Claim 1
Independent Claim
130 words
THE PROCESS OF PRODUCING A HIGH-QUALITY POLYMER COMPRISING SUSPENDING A POLYMERIZABLE MONOETHYLENIC MONOMER IN WATER, THE WATER-MONOMER RATIO BEING ABOUT 1.50-4:1 BY AGITATION WITH THE AID OF ABOUT 0.025 TO 1.0% BY MONOMER WEIGHT OF THE WATER-DISPERSIBLE NON RESINOUS REACTION PRODUCT OF UP TO 15 PARTS OF A RESINFORMING DICARBOXYLIC ACID, 20 TO 40 PARTS OF A POLYGLYCEROL AND 45 TO 75 PARTS OF AN ACID SELECTED FROM THE GROUP CONSISTING OF NONDRYING MONOBASIC ACIDS, CYCLOALIPHATIC ACIDS AND MIXTURES OF THESE ACIDS AND WHILE CONTINUING THE AGITATION, SUSPENSION POLYMERIZING SAID MONOMER AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 105*-160*F. IN THE PRESENCE OF ABOUT 0.10% TO 0.40% BY MONOMER WEIGHT OF A POLYMERIZATION CATALYST FOR SAID MONOMER, AND THEREAFTER SEPARATING THE SUSPENDED POLYMER FROM SAID WATER BY DISCONTINUING AGITATION.
