UNIAXIAL ELONGATIONAL VISCOSITY OF POLY (STYRENE-BLOCK-BUTADIENE-BLOCK-STYRENE) MELTS

Medical applications of poly(styrene-block-isobutylene-block-styrene) ("SIBS").

Poly(Styrene-block-IsoButylene-block-Styrene) ("SIBS") is a biostable thermoplastic elastomer with physical properties that overlap silicone rubber and polyurethane. Initial data collected with SIBS stent-grafts and coatings on metallic stents demonstrate hemocompatibility, biocompatibility and long-term stability in contact with metal. SIBS has been used successfully as the carrier for a drug-...

Three-dimensional study of cylindrical morphology in a styrene-butadiene-styrene block copolymer

When a block copolymer undergoes microphase separation, well ordered microstructures result which give the copolymer unique thermal and mechanical properties. In relating these properties quantitatively to the microstructure, and in devising models for the phase separation, theoreticians have always invoked highly idealized structural elements. However, variations in the actual microstructure m...

Styrene-butadiene-styrene Tri-block Copolymers Modified with Polyhedral Oligomeric Silsesquioxanes

The development of a micro‐shunt made from poly(styrene‐block‐isobutylene‐block‐styrene) to treat glaucoma

Glaucoma is the second leading cause of blindness with ∼70 million people worldwide who are blind from this disease. The currently practiced trabeculectomy surgery, the gold standard treatment used to stop the progression of vision loss, is rather draconian, traumatic to the patient and requires much surgical skill to perform. This article summarizes the more than 10-year development path of a ...
