PROCESS FOR CRYSTALLIZING POLYETHYLENE NAPHTHALATE
摘要
Polyethylene naphthalate pellets coated with an alkylene carbonate such as ethylene carbonate or propylene carbonate crystallize more quickly and at lower temperature than uncoated pellets, reducing the tendency of the pellets to stick together during the crystallization process prior to solid-state polymerization.
