히드로퀴논 비스(2-히드록시에틸)에터

개요Hydroquinone bis(2-hydroxyethyl) ether (HQEE) is a kind of polyurethane chain extender synthesized by hydroquinone (HQ) and ethylene oxide (EO). With different molar ratios of hydroquinone bis(2-hydroxyethyl)ether (HQEE)/1,4-butanediol 9/91, 18/82 and 27/73, a series of thermoplastic poly(butylene-co-hydroquinone bis(2-hydroxyethyl)ether terephthalates) (PBHT) were synthesized via melt polycondensation. The incorporation of the HQEE group significantly improved the thermal properties of the polymers. However, HQEE did not change the crystal structure of PBT. The Tm values of the copolymers decreased (from 208°C to 174°C) with increasing content of HQEE segments, on the contrary, Tg values increased (from 37°C to 43°C)[1-2].
