Method of preparing aqueous latex of high molecular weight vinylbenzyl halide polymer and resulting product

Claim 1

A METHOD FOR MAKING AN AQUEOUS LATEX OF A HIGH MOLECULAR WEIGHT POLYMERIC VINYLBENZYL HALIDE OF THE GROUP CONSISTING OF LINEAR AND CROSSLINKED POLYMERS HALIDE BEING A MEMBER OF THE GROUP CONSISTING OF CHLORIDE AND BROMIDE, COMPRISING HEAT REACTING AT A TEMPERATURE BETWEEN ABOUT 10* AND 30*C. IN AN INERT ATMOSPHERE AN OIL-IN-WATER EMULSION CONTAINING BETWEEN ABOUT 5 AND ABOUT 50 WEIGHT PERCENT, EMULSION BASIS, OF MONOMER OF THE GROUP CONSISTING OF (A) VINYLBENZYL HALIDE; (B) AT LEAST ABOUT 5 WEIGHT PERCENT OF VINYLBENZYL HALIDE, THE BALANCE BEING AT LEAST ONE MONOALKENYL MONOMER OF THE GROUP CONSISTING OF STYRENE AND MONOALKENYL MONOMERS COPOLYMERIZABLE WITH STYRENE; AND (C) MIXTURES OF ONE OF (A) AND (B) WITH UP TO 1 WEIGHT PERCENT OF A CROSSLINKING AGENT CONTAINING TWO VINYLIDENE GROUPS, IN THE PRESENCE OF ABOUT 0.5 TO ABOUT 10 WEIGHT PERCENT, MONOMER BASIS, OF A SYNTHETIC ORGANIC, PH STABLE, ANIONIC EMULSIFIER, ABOUT 0.1 TO ABOUT 1 WEIGHT PERCENT, MONOMER BASIS, OF A WATER-SOLUBLE PEROXY INITIATOR, AND ABOUT 0.1 TO 1 WEIGHT PERCENT, MONOMER BASIS, OF A WATER-SOLUBLE REDUCING ACTIVATOR TO FORM A POLYMERIC LATEX HAVING POLYMER PARTICLE DIAMETERS RANGING BETWEEN ABOUT 200 A. AND ABOUT 3000 A. AND HAVING MOLECULAR WEIGHTS RANGING BETWEEN ABOUT 20 MILLION AND ABOUT 10 BILLION FOR THE CROSSLINKED POLYMERS AND HAVING INTRINSIC VISCOSITIES BETWEEN ABOUT 0.9 AND 2.5 FOR THE LINEAR POLYMERS.

Claim 2

A METHOD FOR MAKING AN AQUEOUS LATEX OF A HIGH MOLECULAR WEIGHT POLYMERIC VINYLBENZYL HALIDE OF THE GROUP CONSISTING OF LINEAR AND CROSSLINKED POLYMERS HALIDE BEING A MEMBER OF THE GROUP CONSISTING OF CHLORIDE AND BROMIDE, COMPRISING HEAT REACTING AT A TEMPERATURE BETWEEN ABOUT 10* AND 30*C. IN AN INERT ATMOSPHERE AN OIL-IN-WATER EMULSION CONTAINING BETWEEN ABOUT 5 AND ABOUT 50 WEIGHT PERCENT, EMULSION BASIS, OF MONOMER OF THE GROUP CONSISTING OF (A) VINYLBENZYL HALIDE; (B) AT LEAST ABOUT 5 WEIGHT PERCENT OF VINYLBENZYL HALIDE, THE BALANCE BEING AT LEAST ONE MONOALKENYL MONOMER OF THE GROUP CONSISTING OF STYRENE AND MONOALKENYL MONOMERS COPOLYMERIZABLE WITH STYRENE; AND (C) MIXTURES OF ONE OF (A) AND (B) WITH UP TO 1 WEIGHT PERCENT OF A CROSSLINKING AGENT CONTAINING TWO VINYLIDENE GROUPS, IN THE PRESENCE OF ABOUT 0.5 TO ABOUT 10 WEIGHT PERCENT, MONOMER BASIS, OF A SYNTHETIC ORGANIC, PH STABLE, ANIONIC EMULSIFIER, ABOUT 0.1 TO ABOUT 1 WEIGHT PERCENT, MONOMER BASIS, OF A WATER-SOLUBLE PEROXY INITIATOR, AND ABOUT 0.1 TO 1 WEIGHT PERCENT, MONOMER BASIS, OF A WATER-SOLUBLE REDUCING ACTIVATOR TO FORM A POLYMERIC LATEX HAVING POLYMER PARTICLE DIAMETERS RANGING BETWEEN ABOUT 200 A. AND ABOUT 3000 A. AND HAVING MOLECULAR WEIGHTS RANGING BETWEEN ABOUT 20 MILLION AND ABOUT 10 BILLION FOR THE CROSSLINKED POLYMERS AND HAVING INTRINSIC VISCOSITIES BETWEEN ABOUT 0.9 AND 2.5 FOR THE LINEAR POLYMERS.
