Equilibrium phase diagrams of mixtures of propoxylated glyceroltriacrylate (GFTA) and low molecular weight liquid crystals (LMWLCs) are investigated. The experimental phase diagrams of monomeric and electron beam (EB) cured GPTA/LMWLC blends are established by polarized optical microscopy (POM). Three LMWLC are used exhibiting different nematic-isotropic transition temperatures. One is the single component LMWLC 4-cyano-4'-n-pentyl-biphenyl (5CB), another one is the eutectic mixture known as E7, and the third one is the single component 4-cyano-4'-n-octyl-biphenyl (8CB) exhibiting both nematic and smectic A orders, The experimental data are successfully analyzed within a unified theoretical treatment based on mean field approximations.
