Abstract:
A process for preparing a composition comprising a mixture with ester and amine functions in the form of ester-amines, amines, salts of amines, monoglycerides, and diglycerides all derived from- monomeric, dimeric, trimeric, and/or tetrameric fatty acids contained in a polymerized polyunsaturated, natural, vegetable or animal oil and wherein at least one of said amine functions is a tertiary amine, comprising:(a) polymerizing a polyunsaturated vegetable or animal oil to form a polymerized oil, (b) treating said polymerized oil by entrainment with water vapor by passing a stream of dry water vapor over the polymerized oil, in a quantity of 5 to 30% by weight relative to the oil, at 180 to 250Â° C., under a vacuum of 7 to 2.5 kPa and for a period of 1 to 5 hours, and (c) reacting said polymerized oil with an excess of at least one compound containing at least one hydroxyl function and at least one tertiary amine function, optionally in the presence of a catalyst.
