摘要：

The invention concerns the production of a voluminous, particulate vinyl chloride polymer by precipitation of a solution of the polymer in a heated, agitated nonsolvent with removal of the solvent by distillation, the nonsolvent exhibiting a boiling point of > 100° C. under normal pressure, and the temperature of the nonsolvent being 40°- 120° C. above the boiling point of the solvent, but does not fall below 100° C. nor range above 180° C. The voluminous, particulate polymer is suitable for the production of damping materials.
