SURFACE TREATMENT OF ETHYLENE-BASED POLYMER PELLETS TO IMPROVE BLOCKING RESISTANCE |
摘要 |
<p>The method of this invention for raising the stick temperature of pellets of ethylene-based copolymers with an acid content at least 5 weight percent has the steps of contacting the pellets with an aqueous solution of a water-soluble metal salt of an aliphatic acid having fewer than 12 carbon atoms, and drying the pellets. The resulting ethylene-based copolymers have a stick temperature of above 25 DEG C and preferably at least 5 DEG C above that of the untreated pellets.</p> |
