AMINIMIDE COMPOSITIONS Russian patent published in 2020 - IPC C09D163/00 C08G59/40 C08G59/44 C07C319/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing aminimide. Epoxy compound reacts with a hydrazine compound containing trivalent nitrogen and a cyclic compound containing a carbonyl group and at least one nitrogen or sulphur heteroatom located in the alpha position to a carbonyl group, or first oxygen heteroatom located in alpha position to carbonyl group, and second heteroatom of oxygen, nitrogen or sulphur, located in alpha position to carbonyl group, at temperature higher than 20 °C to form aminimide, where epoxy compound is polyepoxide. Present invention also describes an adhesive composition comprising an epoxy compound and a polymer compound containing at least two aminimide functional groups, said polymer compound is present in amount of 2–8 wt. % with respect to the total weight of the adhesive composition and reacts with the epoxy compound when activated by an external power source. Adhesive composition can also contain an aminimide salt.

EFFECT: invention provides sufficient binding force and ease of application of adhesive composition when materials are connected to each other.
