| titleOfInvention | Method for drying polymers |
| abstract | This application discloses a method of drying polymers and specifically concerns a method of drying hydroxypropyl cellulose acetate. Other polymers which tend to stick ball or cake significantly during conventional drying may be dried using this disclosure. The polymer to be dried must contain from 5 to 75% volatiles and may contain organic solvents. The process includes the steps of adding from 0.1% to 10% (on a dry solids basis) of a hydrophobic silane-derivatized silicon dioxide in finely powdered form to the polymer to be dried; mixing the materials to make the normally sticky polymer substantially free flowing in nature; and drying the product in a conventional manner. |
