Abstract

This work extends the authors' investigation son liquid crystalline epoxy resins prepared from diglycidyl ether of 4,4'-dihydroxybiphenyl and aliphatic dicarboxylic compounds or difunctional aromatic compounds. Syntheses and properties of these liquid crystalline epoxy resins are described elsewhere. In this paper a study on the curing reaction of two from the above mentioned liquid crystalline epoxy resins is presented. Ortho-tolylbiguanide was applied as the curing agent. The curing reactions were investigated by differential scanning calorimetry, microscopic observations and IR spectroscopy. Depending upon the temperature program of curing, it was possible to obtain polymeric networks with liquid crystalline order.
