Phase behavior of electron beam cured and uncured propoxylated glyceroltriacrylate/E7 mixtures

Polymer Bulletin Aims and scope Submit manuscript

Summary

The phase properties of uncured and electron beam cured propoxylated Glyceroltriacrylate (GPTA)/E7 mixtures are investigated using polarized optical microscopy and differential scanning calorimetry. The cured samples were prepared by polymerization/crosslinking reactions with controlled dose and dose rate by means of electron beam irradiation. The experimental phase diagram of cured GPTA/E7 mixtures was successfully analyzed using a model based on the Flory-Rehner elastic free energy supplemented with the Maier-Saupe free energy of nematic order. The data corresponding to the uncured samples were successfully interpreted combining the Flory-Huggins theory of isotropic mixing and the Maier-Saupe theory of nematic order.
