CONTINUOUS PROCESS FOR PREPARING A POLYURETHANE LATEX |
| 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 solids (between about 65 % and 74 % solids) latex of a polyurethane/urea/thiourea prepolymer, then contacting the emulsion with a chain-extending reagent under such conditions to form the polymer latex.
