Abstract
PURPOSE: To prepare a propylene polymer excellent in the resistance to the sagging of the sheet in the forming, surface roughening and impact resiatance, by carrying out the polymerization in one setp in the presence of a specific Ziegler catalyst.
CONSTITUTION: Propylene or its mixture with ethylene and/or the other α-olefins is polymerized in one step in the presence of a Ziegler catalyst consisting mainly of a transition metal and an organoaluminum compuund to give a propylene polymer for vacuum and pressure forming, having a melt index of 0.1 W 20 g/10 min at 230°C and a load of 2.16 kg, the relationship between the zero-shear viscosity (ηo, poise) at 230°C and the metal viscosity (η, poise) at the shear rate of 1 × 102/sec expressed by the equation, and a propylene content of ≥ 90 wt. %.
