Abstract

1,052,090. Polypropylene films; moulding polypropylene. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 21, 1964 [Aug. 23, 1963], No. 34293/64. Headings B5A and B5B. [Also in Division C3] A process for producing an article of a crystalline polymer of propylene having improved physical and mechanical properties, comprises subjecting the complete article having a thickness of at least 1À25 mm. to application of mechanical pressure in the direction of its thickness at 0‹ to 80‹ C. until the thickness of the article has been reduced by from 10 to 95% of the original article. The article may be in the form of sheet, film, strip, bars, discs or rods, and the mechanical pressure may be biaxial rolling, pressure in a closed die, swaging or drawing. The articles optionally may be subsequently subjected to heat treatment causing shrinkage.
