  • Publication number: 20220112151
    Abstract: A method forming a blocked 1,1-dicarbonyl substituted comprises reacting an alkene of a 1,1-dicarbonyl substituted alkene with a blocking Michael addition donor compound such as an alcohol or thiol. The blocked 1,1-dicarbonyl substituted alkene may be polymerized by providing sufficient thermal energy whereby at least portion of the blocked alkenes revert to alkenes and may be addition polymerized or Michael added with a multifunctional Michael addition donor compound (e.g., polyol or polythiol).
