Title:
IMIDE-TERMINATED PREPOLYMER, PREPARATION METHOD THEREFOR, CURABLE RESIN COMPOSITION, USE THEREOF AND DUAL CURING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/140909
Kind Code:
A1
Abstract:
Provided are an imide-terminated prepolymer, a preparation method therefor, a curable resin composition, use thereof and a dual curing method. An end-capped, imide-terminated prepolymer is mixed with at least one photopolymerizable ethylenic monomer, at least one photoinitiator and diamine, and optionally a pigment to form a curable resin composition. In a first step, irradiation is performed under conditions effective to polymerize the at least one ethylenic monomer. The irradiated composition is then heat-treated under conditions effective to cause a transimidation reaction between the prepolymer and the diamine to provide a solid polymer. When the prepolymer and the composition formed therefrom are used in 3D printing, a 3D printed article can have excellent mechanical properties.
