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-...
متن کاملLiving cationic sequential block copolymerization: synthesis and characterization of poly(4-(2-hydroxyethyl)styrene-b-isobutylene-b-4-(2-hydroxyethyl)styrene) triblock copolymers
INTRODUCTION With the development of living cationic polymerization of isobutylene (IB)1 and styrenic monomers,2–5 the synthesis of ABA triblock copolymer thermoplastic elastomers (TPEs) with polyisobutylene (PIB) as rubbery middle segments and styrenic polymers as plastic outer segments became possible. TPEs with PIB rubbery segments inherently exhibit superior oxidative, chemical and thermal ...
متن کاملThe 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 ...

متن کاملThree-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...
