摘要
Resins and formulations of individual monomers bearing both vinyl ester and epoxy functionality were either synthesized or formulated such that vinyl ester components capable of polymerizing by photo-induced, free radical polymerization were mixed with step-growth epoxy-amine systems, facilitating sequential cure. The vinyl ester component was photopolymerized using vat photopolymerization (VPP). Additionally, the preparation of bio-based photo curable thermosetting resins that have tailorable thermal and mechanical properties is provided. All monomers and polymers described herein are useful in a variety of applications, including additive manufacturing applications.
