A butyl polymer composition having improved cold flow properties is described. The composition comprises a butyl polymer (preferably a halogenated butyl polymer) and a styrene monomer. The styrene monomer is a copolymer of .alpha.- methylstyrene and another styrenic monomer (e.g., styrene and vinyl toluene). Relative to the base butyl polymer, the cold flow properties of the butyl polymer composition are improved along with a number of other properties.
