Thermoplastic elastomer compositions having biorenewable content

摘要

Thermoplastic elastomer compositions, in particular derived from one or more styrenic block copolymers, a plurality of biorenewable materials, preferably a softener and one or more synergistic additives such as a polar polymer; a synergistic block copolymer such as a relatively high molecular weight styrenic block copolymer; and/or filler. In one preferred embodiment, the styrenic block copolymer comprises a controlled distribution copolymer block including a conjugated diene and a mono alkenyl arene. Numerous desirable articles can be formed from the compositions. Processes for preparing the compositions and articles are disclosed.
