Abstract
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 phosphonium or phosphonium salt; 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.
Claims14
A catalyst that reduces polymeric fouling, the catalyst system comprising:
- at least one titanate compound;
- at least one aluminum compound;
- and
- an antifouling agent, where the antifouling agent is an ester comprising a cyclic moiety;
- wherein a molar ratio of total titanate compound to total aluminum compound is from 1:10 to 1:1, where the antifouling agent comprises one or more of ε-caprolactone and 2-phenylethyl acetate, and where a molar ratio of total titanate compound to total antifouling agent is from 1:10 to 1:0.01.
