[Continued on next page] (54) Title: A CATALYST COMPOSITION AND A PROCESS FOR MAKING ULTRA HIGH MOLECULAR WEIGHT POLY (ALPHA-OLEFIN) DRAG REDUCING AGENTS (57) : A method of producing ultra high molecular weight (UHMW) C4-C30 a-olefin drag reducing agent (DRA). The method in- in first in cludes polymerizing a reactor a a-olefin monomer the presence 100 of catalyst and hydrocarbon solvent to produce the DRA. The catalyst FIG.] consists essentially of at least one tertiary monophenyl amine having a i formula R 1 R 2 N-aryl, where R 1 and R 2 are the same or different, and each DELIVER FIRST MONOMER a-OLEFIN is a hydrogen, an alkyl, or a cycloalkyl where at least one of R 1 and group, 110 AND SECOND a-OLEFIN MONOMER R 2 contain at least one carbon atom; at least one titanium halide having a TO REACTOR formula TiX„„ where m is from 2.5 to 4.0 and X is a halogen containing least having foiinula AlR„Y 3 _„ R is moiety; and at one cocatalyst a where a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-20. Further, ACTIVATE f120 the catalyst is absent of a carrier or support.
