DIALDIMINE, DIALDIMINE-CONTAINING EMULSION AND TWO-COMPONENT POLYURETHANE COMPOSITION AND USE THEREOF Russian patent published in 2013 - IPC C07C249/02 C07C275/00 C07C251/02 C09D175/00 C08G18/12 C08G71/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a dialdimine of formula , where R is a radical of formula , where R¹ and R² are either independently univalent hydrocarbon radicals with 1-6 C atoms; R³ is a hydrogen atom; R⁴ is a radical of formula , where R⁵ is a linear or branched alkyl radical with 1-12 C atoms, A is a C₄-C₁₀ diamine group DA with two primary aliphatic amino groups after removal of both primary aliphatic amino groups and containing two ether groups, Q is a diisocyanate group DI after removal of both isocyanate groups; n equals 0 or an integer from 1 to 15; and where A and R do not contain groups which, in the absence of water, are capable of reacting with isocyanate groups. The invention also relates to a method of producing said dialdimine and use of dialdimine in emulsions for use as a curing or accelerating component for polymers with isocyanate groups.

EFFECT: invention provides two-component compositions which are fast-hardening and have exclusively high strength in the early period and do not have undesirable weak points.
