Patent ID: 8138236

Claim:
A liquid moisture activated solvent-free latent curing adhesive or sealant mixture comprising a poly(alkylene oxide)imine represented by formula I: wherein R 1 is a linear or branched C 1 to C 14 residue optionally having one or more heteroatoms of a polyol that is selected from the group consisting of pentaerythritol, glycerol, tetra(2-hydroxypropyl)ethylenediamine and poly(alkylene oxide); R 2 and R′ 2 are, independently of one another, a C 1 -C 4 alkyl group; R 3 and R′ 3 are, independently of one another, hydrogen or methyl group and different from one another, and for a liquid poly(alkylene oxide)imine sample, the average value for a 1 is between 3 and 20, inclusive; and the average value for a 2 is between 1 and 3, inclusive and the average value for f is between 2 and 6, inclusive; and an amine reactive moiety represented by Formula II: wherein R 3 is a linear or branched C 1 to C 14 residue of a polyol, each R 3 is bound to number of f 3 reactive pendant chains and wherein the polyol is selected from the group consisting of pentaerythritol, glycerol, and poly(alkylene oxide), wherein the number of f 3 reactive pendant chains is at least 2 but not greater than 6 and a 3 is at least 3 but not greater than 10; and R 3 ′ is a linear or branched C 1 -C 4 alkylene group optionally having one or more oxygen atoms; and X is an isocyanate group, wherein the poly(alkylene oxide)imine and amine reactive moiety components are liquid under ambient conditions and present in the adhesive or sealant mixture in their neat forms.
