Abstract:
Some embodiments relate to a dual cure polymerization system combining aza-Michael addition polymerization and photopolymerization. Some embodiments also relate to a dual cure polymerization system for preparing interpenetrating polymer networks. Some other embodiments relate to compositions and articles obtainable by a process of the invention and uses thereof.

Claim (Index 16):
A dual cure polymerization process, comprising:\n (i) providing a mixture including: an electrophile monomer (I) having the structure: an electrophile monomer (II) having the structure: wherein EWG 1A  and EWG 1B  independently represent an electron withdrawing group which may contain one or more additional Michael acceptor double-bonds and/or radically polymerizable double bonds; a nucleophile monomer, R 3A \u2014NH\u2014R 3B , bearing a primary or secondary amine functional group wherein R 3A  represents C 1-20 alkyl, C 2-20 alkenyl, C 2-20 alkynyl, C 1-20 heteroalkyl, C 2-20 heteroalkenyl, C 2-20 heteroalkynyl, C 7-20 aralkyl, C 6-10 aryl, or 5 or 6-membered heteroaryl; R 3B  represents H, C 1-20 alkyl, C 2-20 alkenyl, C 2-20 alkynyl, C 1-20 heteroalkyl, C 2-20 heteroalkenyl, C 2-20 heteroalkynyl, C 7-20 aralkyl, C 6-10 aryl, or 5 or 6-membered heteroaryl; wherein each of the foregoing groups may be substituted with \u2014NH 2 , halogen, \u2014CN, C 1-6 alkyl, \u2014OR 2A  where R 2A  represents C 1-6 alkyl; and each of the alkyl, alkenyl and alkynyl moieties may be linear, branched or cyclic; wherein the Michael acceptor double-bonds of the electrophile monomer (I) are in stoichiometric amount relative to the primary amine functional groups of the nucleophile monomer; and wherein the electrophile monomer (II) is unreactive towards Michael addition of the nucleophile monomer; (ii) allowing the nucleophile monomer to undergo Michael addition with the electrophile monomer (I) under suitable conditions thereby forming a first Michael adduct (I A ) having the structure: and\n (iii) subjecting the product obtained in step ii) to a suitable light source to effect photopolymerization of monomer (II), thereby forming an interpenetrating polymer network.
