Application

Hydroquinone bis(2-hydroxyethyl) ether is a white to off-white crystalline powder or flake that serves as an important polyurethane chain extender, synthesized from hydroquinone and ethylene oxide. Its primary purpose is to enhance the thermal properties of polymers, even as it maintains the crystal structure of polybutylene terephthalate (PBT). The material is crucial in the production of a series of thermoplastic poly(butylene-co-hydroquinone bis(2-hydroxyethyl) ether terephthalates) (PBHT) through melt polycondensation. As the content of HQEE increases, the melting temperature of the copolymers is reduced from 208°C to 174°C, while the glass transition temperature rises from 37°C to 43°C, providing improved thermal characteristics without altering the fundamental crystalline nature of PBT.
