Crosslinkers based on 2-acetyl-glutarate esters of polyols.

摘要

Provided are various 2-acetylglutarate esters of polyols which are useful as polymer 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 wherein R is t-butyl, t-amyl, or phenyl; R' is a di, tri, or tetrafunctional polyol residue; and x is an integer of from 2 to about 5.
