Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
161 words
IN THE PROCESS OF MANUFACTURING A STABLE SYNTHETICPOLYMER LATEX HAVING AFFINITY FOR FIBROUS MATERILS SUCH AS TEXTILES AND PAPER AND HAVING ANY DESIRED PH WITHIN THE RANGE OF ABOUT 1.5 TO 11.5 BY THE POLMERIZATION IN AQUEOUS EMULSION OF A MONOMERIC MATERIAL CONSISTING ESSENTIALLY OF FROM 75 TO 90% BY WEIGHT OF VINYLIDENE CHLORIDE, 5 TO 15% BY WEIGHT OF VNYL CHLORIDE AND 5 TO 15% BY WEIGHT OF AN ALKYL ACRYLATE, THE STEPS WHICH COMPRISE FORMING AN AQUEOUS EMULSION OF SAID MONOMERIC MATERIAL WITH THE EMULSIFYING AGENT N-DODECYL-BETAALAMINE, ADDING TO THE EMULSION A SUFFICIENT QUANTITY OF A NEUTRALIZING AGENT SELECTED FROM THE CLASS CONSISTING OF HYDROCHLORIC ACID AND ALKALI HYDROXIDES TO NEUTRALIZE THE N-DODECYL-BETA-ALANINE AND FORM THE SALT THEREOF AND TO PRODUCE THE DESIRED PH AND THEN AGITATING THE EMULSION IN THE PRESENCE OF A POLYMERIZATION CATALYST AT A TEMPERATURE OF FROM -10*C. TO 80*C. TO EFFECT CONVERSION OF THE MONOMERIC MATERIAL TO POLYMER AND THUS PRODUCE A STABLE LATEX.
