Copolymer polyurethane resin having poly(hydroxycarboxylic acid) segment and pendant carboxyl group, and emulsion and adhesive composition including same |
| abstract |
[Problem] To provide an aqueous dispersion-type biodegradable adhesive which has high initial adhesive strength and which enables the high adhesive strength to be maintained over an extended period without decreasing over time. n [Solution] A copolymer polyurethane resin formed primarily of a structure in which a poly(hydroxycarboxylic acid)polyol (A), a diol compound (B) having at least one carboxyl group in each molecule thereof, a monohydric or polyhydric alcohol compound (C) other than (A) and (B), and a diisocyanate compound (D) are bonded by a polyaddition reaction, the copolymer polyurethane resin being characterized in that the poly(hydroxycarboxylic acid)polyol is composed primarily of an L-lactic acid residue and a residue of an aliphatic hydroxycarboxylic acid other than L-lactic acid, and that the weight fraction of the (B) residue is 1-6% and the weight fraction of the (C) residue is 0-50% with respect to a weight fraction of 100% of the (A) residue. An emulsion and adhesive composition composed primarily of the copolymer polyurethane resin and water. |
