Star-epoxy mesogen with 1,3,5-triazine core: a model of A4B3 fractal polymerization in a liquid crystalline thermoset media

Abstract

A star-epoxy monomer (TriaEP) has been synthesized by the creation of a 1,3,5-triazine core. Its association with an aromatic di-amine reveals an A₄B₃ cross-linked polymer that exhibits a complex mechanism of self-assembly. These architectural aspects, resulting from both fractal polymerization and mesophase growth, are discussed in regard to its outstanding thermo-mechanical properties.
