Abstract

1,267,604. Olefin polymers. ESSO RESEARCH & ENG. CO. 1 Aug., 1969 [16 Sept., 1968], No. 38644/69. Heading C3P. [Also in Division C5] Additives for improving the flow characteristics of crude petroleum comprise of polymer of molecular weight 500 to 125,000 and comprising 20 to 100 weight per cent of a C 18-40 α-olefin and 0 to 80 weight per cent of C 3-16 α-olefin, or aryl or cycloaliphatic derivative thereof, and/or a C 6-28 diolefin, which may be prepared by polymerization in inert hydrocarbon diluents in the presence of catalysts comprising a compound of a Group IV, V or VI metal and an organo compound of a Group I, II or III metal. Many suitable monomers are listed and examples describe the preparation in the presence of catalysts comprising aluminium activated titanium trichloride and aluminium triethyl or tripropyl of polymers of (1) n-eicosene-1 (2) propylene and C 22-28 α-olefins, (3) butene-1 and C 22 α-olefin and (4) octadecene-1/propylene, eicosene-1/propylene, docosene-1, docosene-1/ butene-1, docosene-1/hexene-1, docosene-1/ hexene - 1/dicyclopentadiene, docosene - 1/ hexene-1/methylene norbornene, docosene- 1/ styrene, C 22-28 ½-olefin/styrene and C 22-28 a-olefin/4-methylpentene-1.
