Abstract
This application relates to methods and systems for drying polyol starters, as well as reaction mixtures including such polyol starters, and the preparation of polymers derived from such polyol starters. In some embodiments, the present invention encompasses methods of drying a polyol initiator compound, the method including the step of contacting a composition comprising a polyol initiator compound with one or more molecular sieves.
Claims7
A method of drying a polyol initiator compound, the method comprising the step of:
- flowing a composition comprising a polyol initiator compound through a vessel at a flow rate of about 0.5 to about 2.5 mL/min;
- and
- contacting the composition comprising the polyol initiator compound with one or more molecular sieves,
- wherein the vessel contains the molecular sieves and wherein the molecular sieves are maintained at a temperature between about 50° C. and about 100° C. while in contact with the polyol initiator compound.
