Abstract

Invenţia se referă la un procedeu de obţinere a unor copolimeri etilen-propilenici. Polimerizarea se realizează în prezenţa unui sistem catalitic, într-un mediu de reacţie în care polimerul este insolubil, la o temperatură de -5...65°C, timpul de contact fiind de 10 min...6 h, în prezenţă de hidrogen, la o presiune totală de 5...10 bari, raportul între presiunea parţială de etilenă şi presiunea parţială de hidrogen fiind de peste 4.
