Abstract
PURPOSE: To obtain a transparent sheet similar in the physical property to a biaxially stretching sheet with an excellent heat moldability and impact strength by multi- stage rolling of a raw polyproplylene sheet with a specified rolling factor at a specified temperature.
CONSTITUTION: A raw polypropylene sheet (preferably, a propylene-ethylene random copolymer containing 0.05W10wt% of ethylene) in rolled to 1.3W2.5 times length with a rolling roller with a temperature of the melting point of the polyproplylene (hereafter expressed by T°C)WT+30° in the take-up direction and then, rolled with a rolling roll at a temperature below T°C to 1.05W1.8 times length in the take-up direction. It is desirable that the sheet temperature is below 120°C prior to the first-stage rolling.
