Synthesis of Bis(4'-hydroxyphenyl)-toluene-2, 4-diurethane for Main Chain Liquid Crystalline Poly(urethane-ester)s

Received Date: 18 December 1997

A new methodology was advanced that mesogenic cores appeared after the formation of urethane groups and during the monomer-to-polymer transition. A new diphenol monomer, bis(4'-hydroxy-phenyl)-toluene-2,4-diurethane (BHPTU), was obtained by the reaction of 2,4-tolulene diisocyanate with hydroquinone in dioxane or N,N-dimethyl-acetamide. The reaction process was monitored by FTIR, and the product was investigated by ¹HNMR and elemental analysis (EA). A liquid crystalline poly(urethane-ester) was obtained using the BHPTU monomer.
