Sequential dual-curing of electron-deficient olefins and alcohols relying on oxa-Michael addition and anionic polymerization

Abstract

Herein we propose the preparation of crosslinked polymers from off-stoichiometric oxa-Michael formulations proceeding via a self-limiting base catalyzed reaction between difunctional Michael acceptors and substoichiometric amounts of diols followed by anionic polymerization of the remaining vinyl groups. The properties of the resulting polymers can easily be tuned by varying the amount of diols.
