Abstract
PURPOSE:To provide an adhesive having excellent adhesive strength to a soft polyvinyl chloride resin, by blending a soln. of a particular polyurethane polyol having hydroxyl groups at both terminals thereof in an org. solvent with a soln. of a polyfunctional org. isocyanate compd. CONSTITUTION:A crystalline polymer diol (A) having an m.p. of 30-70 deg.C (e.g., a polyester diol prepared from a 4-12C straight-chain alpha,omega-alkanediol and adipic acid) is mixed with poly(beta-methyl-delta-valerolactone) diol (B) in a component (A) to component (B) wt. ratio of 20/80-90/10. The obtd. diol mixture is reacted with an org. diisocyanate (e.g., 2,4-tolylene diisocyanate) to prepare a polyurethane polyol of 5,000-100,000 in number-average MW having hydroxyl groups at both terminals thereof. The title adhesive is produced from a soln. of the polyol in an org. solvent and a soln. of a polyfunctional org. isocyanate compd.
