| titleOfInvention | Catalyst composition and method for preparing ultra-high molecular weight poly(alpha-olefin) drag reducer |
| abstract | The present invention relates to a method for preparing ultra-high molecular weight (UHMW) C 4 -C 30 α-olefin drag reducing agent (DRA). The method includes preparing the DRA by polymerizing a first alpha-olefin monomer in a reactor in the presence of a catalyst and a hydrocarbon solvent. The catalyst consists essentially of the following components: at least one tertiary monophenylamine of formula R 1 R 2 N-aryl, wherein R 1 and R 2 are the same or different and are each hydrogen, alkyl or naphthenic base, wherein at least one of R and R contains at least one carbon atom; at least one titanium halide having the formula TiX m , wherein m is 2.5-4.0, and X is a halogen-containing moiety; and at least one has the formula AlR n Y 3-n cocatalyst, wherein R is hydrocarbyl, Y is halogen or hydrogen, and n is 1-20. Additionally, the catalyst does not contain a carrier or support. |
