Abstract
A curable composition is described comprising a Michael donor component, a polyacryl component, and 1) an ethylenically unsaturated monomer having a reactive azlactone functional group, or 2) an ethylenically unsaturated monomer having a reactive ring-opened azlactone functional group. A telechelic polymer that is the reaction product of these components is also described.
