Abstract

Polimeri e copolimeri cristallini del propilene aventi valori di MIL totale > 2 g/10 minuti, valori di (?) totale in tetralina a 135°C ? 2,8 dl/g, valori di Mw/Mn> 20, contenuto di frazione insolubile in xilene a 25°C ? 94, e comprendenti da 10 a 60% in peso di una frazione (A) avente (?) ? 2,6, vengono preparati mediante polimerizzazione sequenziale in almeno due stadi in presenza di particolari catalizzatori Ziegler-Natta supportati su alogenuri di magnesio.Tali polimeri possiedono elevata "melt-strenght", elevate proprietà meccaniche e sono particolarmente adatti per la produzione di manufatti mediante varie tecnologie di trasformazione, quali ad esempio: estrusione in lastre sottili da sotto-porre a termoformatura, stampaggio a iniezione, blow molding.
