    摘要： An isocyanate-terminated prepolymer having three components. The first component is 30-60 wt % polymerized residues of a first polyol containing a substituent of formula (I) attached via a carbon-carbon single bond to a saturated carbon atom in a fatty acid hydrocarbyl group; wherein R1 and R2 are esterified residues of aliphatic or cycloaliphatic diols; and wherein the first polyol contains: (i) from 0.33 to 0.4 units of formula (I) per fatty acid hydrocarbyl group, and (ii) from 0 to 12 wt % esterified residues of at least one C4-C12 anhydride, C4-C12 diacid or C4-C12 lactone, not including units of formula (I) attached to a fatty acid hydrocarbyl group; and wherein the first polyol has a hydroxyl number from 75 to 150 mg KOH/g. The second component is 40-55 wt % polymerized residues of diphenyl methane diisocyanate. The third component is 0-20 wt % polymerized residues of a glycol having Mn from 300 to 3500.

    摘要： Solvent-based adhesive composition are disclosed, the compositions comprising (A) a polyester-urethane resin, (B) a phosphate ester compound, and (C) an aliphatic isocyanate curing agent. Methods for preparing a solvent-based adhesive composition, the methods comprising providing a polyester-urethane resin, providing a phosphate ester compound, mixing the polyester-urethane resin and phosphate ester compound to form a resin mixture, diluting the resin mixture in a solvent to form a diluted resin mixture having an application solid content of from 25 to 55 weight percent, based on the total weight of the diluted resin mixture, and curing the diluted resin mixture with an aliphatic isocyanate curing agent at a mix ratio (parts by weight resin mixture before dilution:parts by weight aliphatic isocyanate curing agent) of from 100:1 to 100:12. Laminates prepared comprising the solvent-based adhesives and according to the disclosed methods are also disclosed.
