Abstract
1292743 Ethylene-butene copolymers PHILLIPS PETROLEUM CO 23 March 1970 [24 March 1969] 13817/70 Heading C3P Copolymers of ethylene with 5 to 9 weight per cent of butene-1, having a density of 0À920 to 0À930 g./c.c., a molecular weight distribution of 6 : 1 to 20 : 1, an environmental stress cracking (F 50 ) resistance greater than 100 and 14 to 21 ethyl branch groups per 1000 carbon atoms, may be prepared by copolymerizing ethylene and butene-1 in an inert diluent, e.g. isobutane, in the presence of a catalyst formed by impregnating microspheroidal silica or silica/ alumina with chromium trioxide and activating for 5 hours at 1400 F. A modifier, e.g. hydrogen, may also be present.
