摘要： A method of producing ultra high molecular weight (UHMW) C4-C30 α-olefin drag reducing agent (DRA). The method includes polymerizing in a reactor a first α-olefin monomer in the presence of catalyst and hydrocarbon solvent to produce the DRA. The catalyst consists essentially of at least one tertiary monophenyl amine having a formula R1R2N-aryl, where R1 and R2 are the same or different, and each is a hydrogen, an alkyl, or a cycloalkyl group, where at least one of R1 and R2 contain at least one carbon atom; at least one titanium halide having a formula TiXm, where m is from 2.5 to 4.0 and X is a halogen containing moiety; and at least one cocatalyst having a formula AlRnY3-n where R is a hydrocarbon radical, Y is a halogen or hydrogen, and n is 1-20. Further, the catalyst is absent of a carrier or support.

摘要： A catalyst system that may reduce polymeric fouling may include at least one titanate compound, at least one aluminum compound, and an antifouling agent. The antifouling agent may be chosen from one or more of a sulfonate or a sulfonate salt; a sulfonium or sulfonium salt; an ester including a cyclic moiety; an anhydride; a polyether; and a long-chained amine-capped compound. The catalyst system may further include a non-polymeric ether compound.
