POLYTRIMETHYLENE ETHER-BASED POLYURETHANE IONOMERS

摘要

Disclosed is aqueous polyurethane dispersion with a polyurethane having a polymeric backbone with ionic and/or ionizable functionality incorporated into the polymeric backbone. The polymeric backbone consists essentially of one or more non-ionic segments derived from a reaction product of polytrimethylene ether glycol and a diisocyanate. The manufacture of such polyurethanes is also disclosed.
