Dispersion of a preformed polymer in a polyol |
| 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. |
