Abstract
Oligohexamet diglycidyl ether hyleneguanidine (OHMG) stearates and palmitates, which have a higher solubility in epoxy oligomers (EOs) (glycidyl ethers of diphenylolpropane, Epikote 828, and polyglycidyle ether of oligooxypropilene oligooxypropylene polyol, Laproksid 703) than the widely used OHMG hydrochloride has, have been synthesized and characterized. Probably due to the better solubility, pronounced chemical interaction between EOs and OHMG fatty-acid salts occurs to yield adducts of EOs and OHMG, which are completely compatible with an initial EO. It has been proposed to incorporate OHMG fatty-acid salts into epoxy-amine networks via the preliminary synthesis of EO–OHMG adducts.
