摘要： A polyurethane/urea/thiourea latex having a narrow molecular weight polydispersity and sub-micron particle size can be prepared by first preparing a high internal phase ratio (HIPR) emulsion of a polyurethane/urea/thiourea prepolymer, then contacting the emulsion with a chain-extending reagent under such conditions to form the polymer latex.

摘要： A polyurethane dispersion prepared using a two step addition of different surfactants has greater shear stability than a similar dispersion prepared using only a single surfactant or a single step addition of surfactants.

摘要： The present invention provides a process for preparing a stable dispersion of a preformed polymer in a polyol in a single mixer. A preformed polymer is mixed under sufficient heat and shear to reduce its particle size to a desired size in the presence of a polyol. The present invention also provides stable dispersions of polymers in polyols and polyurethane formulations containing stable dispersions made by the process of the present invention.

摘要： The present invention is polyurethane dispersion composition that can be mechanically frothed to yield a foam that has good resiliency. Frothed foams of the present invention can be useful in cushioned flooring applications such as attached cushion broadloom, carpet tiles, carpet underlay, or vinyl flooring. Frothed foams of the present invention can also be useful as coatings for various textiles and for diapers.
