Abstract

Embodiments described herein are directed to polymerization-induced phase-separating (PIPS) compositions for enhancement of impact resistance and rheological properties in photocurable resins for 3D printing, such as for inks, coatings and adhesives. Embodiments described herein are advantageous with respect to properties such as impact resistance, shear adhesion and cohesive strength. The PIPS compositions may include components X, Y and Z, wherein X includes an acrylic based monomer; Y includes a copolymer of block A and block B; and Z includes a multifunctional cross-linker. Methods of using the PIPS compositions are also described. Also described are methods of screening potential acrylic based monomeric or oligomeric additives that yield improved impact resistance.
