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.
Claims15
A polymer of the formula:
- Az-[D-A]y-D-Az
- wherein Az is the residue of an ethylenically unsaturated monomer having a ring-opened azlactone functional group, D is the residue of a Michael donor component, A is the residue of a polyacryl component, and y is at least 1.
