ABSTRACT:
Hydroxy functional, unsaturated diesters are disclosed that comprise the esterification reaction products of unsaturated anhydrides with secondary alcohols to form monoesters, followed by oxyalkylation of the monoester with epoxy compounds, whereby a diester is formed with hydroxy functionality. Use of secondary alcohol yields monoesters less prone to disproportionation. The unsaturated diesters may be copolymerized with vinyl monomers to form hydroxy functional copolymers useful in coating applications, wherein they may be included in compositions along with a curing agent that is reactive with hydroxy groups.
