METHOD FOR CURING ADHESIVE USING MICROWAVE IRRADIATION Russian patent published in 2019 - IPC C09J5/06 C09J11/06 C08F2/46 

FIELD: chemistry.

SUBSTANCE: method for curing a polymer adhesive composition using microwaves and a method for attaching a thermoplastic material are proposed. Said polymer adhesive composition, curable with the use of microwaves, contains ionic liquid [A]⁺_a[B]^a-, at the same time [A]⁺ is a cation, and [B]^a- is an anion, and a is an integer. In this case, the cation [A]⁺ is an ammonium cation [R^1'R¹R²R³N]⁺, cation of phosphonium [R^1'R¹R²R³P]⁺, sulfonium cation [R^1'R¹R²S]⁺, heteroaromatic guanidinium cation R³R^3'N(C=NR¹R^1')NR²R^2', where R¹, R^1', R², R^2' and R³, R^3' represent hydrogen or organic residue. When attaching a thermoplastic material, a thermoplastic material is prepared and applied to the surface of its specified ionic liquid.

EFFECT: invention provides good adhesion of hot melt adhesives containing ionic liquid, the use of which allows to improve the localization of heat supplied by means of microwaves.
