Preparations of reaction products of epoxides,fatty amines and basic polyamides,processes for their manufacture and their use
Abstract
Abstract A PROCESS OF THE MANUFACTURE OF STABLE PREPARATIONS OF WATER-SOLUBLE OR WATER-DISPERSIBLE READTION PRODUCTS OF EPOXIDES, FATTY AMINES AND BASIC POLYAMIDES IS PROVIDED. THE EPOXIDES CONTAINS AT LEAST TWO EPOXIDE GROUPS PER MOLECULE, THE AMINES ARE HIGHER-MOLECULAR WEIGHT FATTY AMINES (H3C-(CH2)X-NH2 WHEREIN X REPRESENTS AN INTEGER HAVING THE VALUE OF 11 TO 23) AND THE POLYAMIDES ARE MADE FROM POLYMERIC UNSATURATED FATTY ACIDS AND POLYALKYLENEPOLYAMINES. THE REACTION IS CARRIED OUT IN THE PRESENCE OF AN ORGANIC SOLVENT AT TEMPERATURES UP TO 95* C. NOT LATER THAN AFTER COMPLETION OF THE REACTION, IT IS ENSURED THAT A SAMPLE OF THE REACTION MIXTURE HAS A PHVALUE OF 2 TO 8 AFTER DILUTION WITH WATER. THE RESULTING REACTION PRODUCTS ARE SOLUBLE IN WATER AND ARE USEFUL IN THE TEXTILES INDUSTRY E.G. FOR RENDERING WOOL NON-FELTING.
