Viskositäterniedrigendes Mittel für aromatische Polyesterpolyole und Polyätherpolyole

Agents réduisant la viscosité de polyester-polyols aromatiques et de polyéther-polyols

Viscosity reducing agents for aromatic polyester polyols and polyether polyols

Abstract

The viscosity of aromatic polyester polyols and polyether polyols is reduced by adding 5% to 15%, based on the weight of the polyol, of a cyclic organic viscosity reducing agent selected from propylene carbonate, ethylene carbonate, mix­tures of ethylene carbonate and propylene carbonate, and caprolactone.
