Robust thermostable polymer composition based on poly[N,N′-(1,3-phenylene)isophthalamide] and 3,3-bis(4-acrylamidophenyl)phthalide for laser 3D printing

A photopolymer composition based on poly[N,N′-(1,3-phenylene)isophthalamide] and 3,3-bis(4-acrylamidophenyl)phthalide was developed and utilized for the formation of 3-dimensional structures using the laser stereolithography method with a high reproducibility and the absence of any autopolymerization effects. The obtained 3D structures were mechanically strong and characterized by a high thermal stability (up to 415°C), which makes them promising as high-tech plastics for constructional purposes.
