摘要： Methods are provided to efficiently produce butyl rubber via a slurry polymerization process. The process comprises providing at least two monomers, wherein at least one monomer is an isoolefin and at least one monomer is a multiolefin. The monomers are combined with an initiator and an organic diluent comprising 40-60 volume % of methyl chloride and 40-60 volume % of 1,1,1, 2-tetrafluoroethane and polymerized.

摘要： A BrønstedLowry acid initiator system for cationic polymerization of an ethylenically unsaturated monomer involves an initiator having a structure of Formula (I) in an anhydrous polymerization medium (I) where: M is tantalum (Ta), vanadium (V) or niobium (Ni); each R1 is independently H, OR6, F, Cl, Br, I or alkyl, where R6 is H or alkyl; R2, R3, R4 and R5 are independently H, F, Cl Br, I, alkyl or aryl, or two or more of R2, R3, R4 and R5 on a same benzene ring form a bicyclic, tricyclic or tetracyclic moiety with the benzene ring, with the proviso that all of R2, R3, R4 and R5 on the same benzene ring are not H; L is absent or a molecule that coordinates to H+; and, x is 0 when L is absent, or x is 0.5 or more when L is present.

摘要： A Brønsted-Lowry acid initiator system for cationic polymerization of an ethylenically unsaturated monomer involves an initiator having a structure of Formula (I) in an anhydrous polymerization medium: where: M is tantalum (Ta), vanadium (V) or niobium (Nb); R1, R2, R3 and R4 are the same or different and are independently H, F, Cl, Br, I, alkyl or aryl, or two or more of R2, R3, R4 and R5 on a same benzene ring are taken together to form a bicyclic, tricyclic or tetracyclic moiety with the benzene ring, with the proviso that all of R1, R2, R3 and R4 on the same benzene ring are not H; L is absent or a molecule that coordinates to H+; and, x is 0 when L is absent, or x is 0.5 or more when L is present.
