POLY(HYDROXYPROPYLENE)GLYCOL GLYCIDYLIC ESTER ALIPHATIC KETIMINES AND METHOD OF THEIR SYNTHESIS Russian patent published in 1997 - IPC

FIELD: chemical technology. SUBSTANCE: product: aliphatic ketimines of poly(hydroxypropylene)glycol glycidylic esters of the formula: $$$ where: n = 0-7; m = 2-3. Aliphatic ketimines were synthesized by interaction of poly(hydroxypropylene)glycol glycidylic esters with ammonia in ketone medium at 25-75 C in autoclave under pressure 3.0 kgf/$$$ (not above) and at mass ratio of poly(hydroxypropylene)glycol glycidylic ester and ketone = 1: (0.5-1.5). Aliphatic ketimines were used as hardening agents for epoxy resins used as anticorrosive coatings. EFFECT: high protective, decorative and elasticity properties. 2 cl
