Abstract

1,272,778. Purifying polyolefins. BADISCHE ANILIN. & SODA. FABRIK A.G. 25 Sept., 1969 [26 Sept., 1968], No. 47150/69. Heading C3P. Volatile constituents are removed from particulate polyolefins prepared by gas phase polymerization by treating a layer of particles of the polymer of particle size 10 to 5000 microns with a stream of inert gas at a temperature of 80‹ C. to at least 5‹ C. below the crystallite melting point of the polymer while in vigorous motion. Specified polymers are of ethylene, propylene and/or butene-1. Specified gases are nitrogen, carbon dioxide and steam. The process is said also to improve the free-flowing properties and increase the bulk density of the polymer. Apparatus for carrying out the process is described and illustrated, and examples describe the treatment of (1) polypropylene, (2) polyethylene and (3) ethylene/butene-1 copolymer with streams of nitrogen.
