AMINOPLASTIC RESINS FOR LAMINAR PLASTICS Russian patent published in 2020 - IPC C08G12/26 C08G12/32 

FIELD: chemistry.

SUBSTANCE: invention relates to high-molecular compounds, specifically condensation polymers of aldehydes or ketones with two or more other monomers, and can be used as structural material both independently and in composites. Aminoplastic resin consists of melamine and substituted glycoluril, cross-linked with aldehydes and curable by heating at pH 3–6, and a stabilizer. Cross-linking agent used is 36.6 % formalin. Substituted glycoluril used is 1,5-dimethylglycoluril, 1,5-diphenyl-2,6-dimethylglycoluril, 1,5-diphenylglycoluril, 2,6-dimethylglycoluril or 1,2,5,6-tetramethylglycoluril.

EFFECT: high thermal and mechanical strength of the aminoplast resin.
