Abstract

Process for obtaining polypropylene sheets, comprising extruding polypropylene, at a mass temperature of 180 to 360º c, to sheets of 0.03 to 8 mm in thickness and 150 to 3000 mm in width, and biaxially stretching the sheets, at a surface temperature which is above 10ºC but below the melting point of the crystallites of the polypropylene used, respectively in the proportions of 1: 2 to 1:15, characterized in that a mixture is used as polypropylene from (a) 70 to 80 parts by weight of a polypropylene of which (with a polypropylene: toluene weight ratio of 5:95) less than 1% by weight (under normal conditions) is soluble in boiling toluene, and (b) ) 20 to 30 parts by weight of a polypropylene of which (with a polypropylene: toluene weight ratio of 5:95) more than 99% by weight (under normal conditions) is soluble in boiling toluene, under the conditions of (I) ) that the sum of the parts by weight of (a) and (b) be respectively of 100, (II) that the polypropylenes of (a) and (b) have both (approximately) the same intrinsic viscosities as well as (approximately) the same molecular weight distributions (determined according to the gel permeation chromatography method) and (III) that the absolute values of the intrinsic viscosities [η] (measured in decalin at 130º c) are respectively in the range of 1 to 10.
