Polyoxyalkylated alkyl phenol-formal-dehyde-alkylene polyamine resins

Claim 1

AN OXYALKYLATED ALKYL PHENOL-FORMALDEHYDE-ALKYLENE POLYAMINE RESIN PRODUCED BY FIRST HEATING A MIXTURE OF FORMALDEHYDE AND AN ALKYL PHENOL SELECTED FROM THE GROUP CONSISTING OF AN ORTHO AND PARA MONOALKYL PHENOL HAVING A 4-15 CARBON ALKYL GROUP, MIXTURES OF SAID MONOALKYL PHENOLS, AND MIXTURES OF SAID MONOALKYL PHENOL WITH UP TO 25% OF O, P-DIALKYL PHENOLS WITH 4-15 CARBONS IN THE ALKYL GROUPS TO PRODUCE A PRECURSOR ALKYL PHENOLFORMALDEHYDE INTERMEDIATE CONDENSATE, FURTHER CONDENSING SAID INTERMEDIATE CONDENSATE BY HEATING IT WITH ADDITIONAL ALKYL PHENOL AS AFOREDEFINED AND FORMALDEHYDE AND ALSO ALKYLENE POLYAMINE HAVING TWO PRIMARY AMINO GROUPS AND ALKYLENE GROUPS OF 2-6 CARBONS, THE TOTAL AMOOUNTS OF SAID ALKYL PHENOL USED IN BOTH OF THE AFORESAID REACTIONS TO SAID ALKYLENE POLYAMINE USED IN THE LATTER REACTION BEING, ABOUT 1:1 TO 10:1, RESPECTIVELY, AND THE TOTAL MOLS OF FORMALDEHYDE USED IN BOTH OF THE AFORESAID REACTIONS TO THE TOTAL MOLS OF BOTH OF SAID ALKY PHENOL USED IN BOTH OF THE AFORESAID REACTIONS AND THE ALKYLENE POLYAMINE USED IN THE LATTER REACTION BEING ABOUT 0.9:1 TO 1.5:1, RESPECTIVELY, AND REMOVING BY DISTILLATION DURING SAID HEATING IN BOTH OF THE AFORESAID REACTIONS THE WATER OF REACTION TO PRODUCE ALKYL PHENOL-FORMALDEHYDE-ALKYLENE POLYAMINE RESIN CHARACTERIZED BY ALKYLENE POLYAMINE UNITS CONNECTED IN THE POLYCONDENSATE CHAIN BY METHYLENE GROUPS ON TWO AMINO NITROGENS; AND OXYALKYLATING SAID RESIN WITH ALKYLENE OXIDE SELECTED FROM THE GROUP CONSISTING OF ETHYLENE OXIDE, 1,2-PROPYLENE OXIDE AND BOTH ETHYLENE OXIDE AND 1,2-PROPYLENE OXIDE IN AN AMOUNT OF THE LATTER SUFFICIENT TO PROVIDE IN THE OXYALKYLATED ALKYL PHENOL-FORMALDEHYDEALKYLENE POLYAMINE RESIN A WEIGHT RATIO OF OXYALKYLENE GROUPS TO SAID ALKYL PHENOL-FORMALDEHYDE-ALKYLENE POLYAMINE RESIN IN THE RANGE OF ABOUT 2:3 TO 10:1, RESPECTIVELY.
