Abstract
Improved surfactants and functional fluids are prepared by reacting a monofunctional initiator with an alkylene carbonate or with an alkylene oxide and carbon dioxide to form polyether polycarbonate materials. As surfactants, the resulting materials exhibit reduced foaming characteristics as compared to other nonionic surfactants. The viscosity-temperature relationships, flash points and pour points make them useful as functional fluids.
