Provided are various 2-acetylglutarate esters of polyols which are useful as poller crosslinkers for use in thermosetting coating compositions, as well as methods of preparation of these materials. In particular, the invention provides crosslinkers of the formula [Figure] wherein R and R′are independently t-butyl, t-amyl, or phenyl, and x is an integer of from 2 to 5.
