The cross-linked poly(aspartic acid) product is a reaction product of a polysuccinimide (PSI), a compound (A: a1-A1-a2) containing a first functional group (a1) and a second functional group (a2), and a polyfunctional epoxy compound (B). The cross-linked poly(aspartic acid) product contains a cross-linked structure (PABAP) represented by PSI-a1-A1-a2-B-a2-A1-a1-PSI, the cross-linked structure (PABAP) is partially hydrolyzed, and the second functional group of the compound (A) does not react with the polysuccinimide (PSI) or is less reactive with the polysuccinimide (PSI) than the first functional group.

Abstract

The present invention provides a moisture-curable polyurethane hot-melt resin composition comprising a urethane prepolymer (i) having an isocyanate group, which is a product of reaction between a polyol (A) and a polyisocyanate (B), and a tackifier (ii), characterized in that the polyisocyanate (B) is a polyisocyanate prepolymer which is a product of reaction between one or more compounds (b1) having a number-average molecular weight less than 500, having a branched structure, and having two to four hydroxyl groups in the molecule and a diisocyanate (b2). The invention further provides a pressure-sensitive adhesive characterized by including the moisture-curable polyurethane hot-melt resin composition.

Abstract

It is an object of the present invention to provide a cross-linked poly (aspartic acid) product that can retain the gel shape, water absorbency, water retentivity, and other performance because it does not undergo hydrolysis over time owing to the absence of an ester bond, and a method for producing the cross-linked poly (aspartic acid) product. The cross-linked poly (aspartic acid) product according to an embodiment of the present invention is a reaction product of a polysuccinimide (PSI), a compound (A: a1-A1-a2) containing a first functional group (a1) and a second functional group (a2), and a polyfunctional epoxy compound (B). The cross-linked poly (aspartic acid) product contains a cross-linked structure (PABAP) represented by PSI-a1-A1-a2-B-a2-A1-a1-PSI, the cross-linked structure (PABAP) is partially hydrolyzed, and the second functional group of the compound (A) does not react with the polysuccinimide (PSI) or is less reactive with the polysuccinimide (PSI) than the first functional group.
