A thermoplastic vulcanizate composition comprises: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane composition comprising a migratory siloxane polymer physically dispersed in a first thermoplastic material and (iv) a second polysiloxane composition comprising a non-migratory, siloxane polymer bonded to a second thermoplastic material.

Thermoplastic vulcanizates

A thermoplastic vulcanizate composition comprises: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane comprising a migratory liquid siloxane polymer; and (iv) a second polysiloxane comprising a non-migratory siloxane polymer bonded to a thermoplastic material.

Thermoplastic elastomer compositions, in particular derived from one or more styrenic block copolymers wherein at least one styrenic block copolymer comprises a controlled distribution copolymer block including a conjugated diene and a mono alkenyl arene, 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. Numerous desirable articles can be formed from the compositions. Processes for preparing the compositions and articles are disclosed.
