    摘要: (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.
