Carboxylated styrene/butadiene latices of a high solids content

Abstract

Abstract CARBOXYLATED STYRENE/BUTADIENE LACTICES HAVING A SOLIDS CONTENT OF ABOUT 30 TO 55 WEIGHT PRECENT WITH A GEL CONTENT LESS THAN ABOUT 1.5 WEIGHT PERCENT GENERALLY LESS THAN ABOUT 1 WEIGHT PERCENT COMPRISING A POLYMERIZATION PRODUCT OF MONOMERS OF: A. ABOUT 45 TO 85 PERCENT BY WEIGHT STYRENE OR SUBSTITUTED STYRENES, B. ABOUT 15 TO 55 PERCENT BY WEIGHT BUTADIENE OR SUBSTITUTED BUTADIENE AND C. ABOUT 0.5 TO 5 PERCENT BY WEIGHT A-B-UNSATURATED CARBOXYLIC ACIDS HAVING 3 TO 5 CARBON ATOMS, WHEREIN THE FOLLOWING COMPONENTS ARE EMPLOYED IN THE POLYMERIZATION: D. ABOUT 0.01 TO 0.5 PARTS BY WEIGHT OF AN ANIONIC EMULSIFIER, BASED ON 100 PARTS BY WEIGHT OF MONOMERS A, B AND C, SELECTED FROM THE GROUP CONSISTING OF ALKYL SULFATES HAVING 10-20 CARBON ATOMS, ALKYL SULFONATES HAVING 10-20 CARBON ATOMS, ALKYLARYL SULFONATES HAVING 8-12 CARBON ATOMS IN THE ALKYL CHAIN, AMMONIUM SALTS OF ASULFOFATTY ACIDS HAVING 10-20 CARBON ATOMS AND ALKALI SALTS OF A-SULFOFATTY ACIDS HAVING 10-20 CARBON ATOMS, E. ABOUT 0.2 TO 2 PART BY WEIGHT OF A NONIONIC EMULSIFIER, BASED ON 100 PARTS BY WEIGHT OF MONOMERS A, B AND C, SELECTED FROM THE GROUP CONSISTING OF POLYGLYCOL ETHERS OBTAINED BY THE REACTION OF ONE MOLE OF FATTY ALCOHOLS HAVING 10-20 CARBON ATOMS WITH 3-30 MOLES OF ETHYLENE OXIDE, ONE MOLE OF ALKYLPHENOLS HAVING 4-12 CARBON ATOMS IN THE ALKYL CHAIN WITH 3-30 MOLES OF ETHYLENE OXIDE OR MIXTURES THEREOF, AND F. ABOUT 0.5-2 PARTS BY WEIGHT OF A WATER-SOLUBLE PEROXYDISULFATE, BASED ON 100 PARTS BY WEIGHT OF MONOMERS A, B AND C.
