Abstract
Thermoplastic elastomer compositions, in particular derived from one or more styrenic block copolymers, a relatively high molecular weight isobutylene-containing (co)polymer, and a biorenewable processing aid. The isobutylene-containing (co)polymer imparts desirable oxygen barrier performance to the composition and the biorenewable processing aid acts as a barrier synergist as well as a processing aid useful during compounding. Low oxygen permeability sealing elements can be formed from the compositions. Processes for preparing the compositions and sealing elements are disclosed.
