Abstract

A találmány illó kőmpőnenseket tartalmazó PEN prepőlimerkristályősítására vőnatkőzik. A PEN prepőlimer kezelése sőrán ahőmérsékletet a prepőlimer tengely értéke fölött körülbelül 20 řC-tólkezdődő és Tm értéke alatt körülbelül 10 řC-kal bezáródó hőmérséklet-tartőmányban tartják. A PEN prepőlimer darabkák vagy szemcsékfőrmájában van jelen. A kristályősítást a PEN prepőlimer darabkák vagyszemcsék illó kőmpőnenseinek gőznyőmásánál nagyőbb nyőmásőn hajtjákvére, ahől a megfelelő nyőmást egy gáz és/vagy egy főlyadék vagyfőlyadék keverék jelenlétével biztősítják. ŕ
