A moisture curable adhesive composition includes an isocyanate-terminated polyurethane prepolymer that is a reaction product of a polyol component and an isocyanate component. The polyol component includes a polylactide polyol that is a reaction product of a lactide and a hydroxyl-functional initiator selected from the group consisting of glycerol, a fatty acid monoglyceride, a fatty acid diglyceride, and combinations thereof.

A polylactic acid resin, a polylactic acid resin composition, a polylactic acid resin film, and a molded article are disclosed. The polylactic acid resin, which includes soft segments containing 0.5 wt % or more of at least one repeating unit selected from a polyester-based polyol repeating unit, a polylactone-based polyol repeating unit, or a polycarbonate-based polyol repeating unit, can lead to improvements in flexibility, transparency, tearing strength, processability, and the like while also providing excellent biodegradability.

(Meth)acrylate-functionalized oligomers having a) an oligomeric backbone comprised of first segments and second segments and b) (meth)acrylate-functionalized end groups are provided. Such oligomers are useful as components of curable compositions. The first segments, second segments and (meth)acrylate-functionalized end groups are linked together by linking moieties derived from a polyisocyanate. The first segments are residues of a first segment precursor containing a plurality of repeating units and a plurality of isocyanate-reactive functional groups and having a number average molecular weight of at least 250 daltons. The second segments are residues of a second segment precursor, different from the first segment precursor, containing a plurality of repeating units and a plurality of isocyanate-reactive functional groups and having a number average molecular weight of at least 250 daltons. The first segment and the second segment exhibit a Hansen Solubility Parameter Distance Relative Energy Difference of at least about 4 and not more than about 9.
