Crystalline olefin polymers and copolymers in the form of spherical particles at high porosity. |
| 摘要 |
<p>Crystalline olefin polymers and copolymers in the form of spherical particles having porosity (expressed in percentage of voids) higher than 15%, with more than 90% of the pores having a pore diameter greater than one micron. These polymeric particulate materials find many applications, including, e.g., the preparation of masterbatches containing significant quantities of additives and/or pigments.</p> |
