Abstract
The properties of a new family of thermoplastic elastomers (TPEs) consisting of a polyisobutylene inner soft segment connected to two polystyrene outer hard segments (S-iB-S) has been investigated from the industrial point of view. The S-iB-S block copolymers exhibited excellent properties, especially in regard to gas permeability and damping behavior as compared to other commercialized block copolymers. These unique block copolymers are promising for gas barrier and/or damping materials.
