Biomedical application of commercial polymers and novel polyisobutylene-based thermoplastic elastomers for soft tissue replacement.
Some general considerations for the design and development of polymers for soft tissue replacement are reviewed from the viewpoint of material science and engineering, with special attention to synthetic materials used in vascular grafts and breast implants. Expand
Biocompatibility and fatigue properties of polystyrene-polyisobutylene-polystyrene, an emerging thermoplastic elastomeric biomaterial.
The results presented in this paper indicate that, in comparison with silicone rubber, SIBS30 has similar biocompatibility and superior dynamic fatigue properties. Expand
Analysis of branched polymers by high resolution multidetector size exclusion chromatography: Separation of the effects of branching and molecular weight distribution
This article presents the SEC analysis of branched polyisobutylene PIB and polystyrene PS with high molecular weight and broad multimodal molecular weight distribution. Both polymers were synthesizedExpand
Mid-IR real-time monitoring of the carbocationic polymerization of isobutylene and styrene
Abstract. The in-situ monitoring of the living carbocationic polymerization of isobutylene (IB) and styrene (St) with a fiber optic Attenuated Total Reflection (ATR) probe in the mid-IR "fingerprint"Expand
Green Polymer Chemistry: Enzyme Catalysis for Polymer Functionalization
Fundamental aspects of chemical reactions biocatalyzed by Candida antarctica lipase B are discussed, and their application to create new functionalized polymers, including the regio- and chemoselectivity of the reactions. Expand
Polyisobutylene : A Most Unusual Polymer
The influence of molecular weight, M, on the fragility and fast dynamics in polyisobutylene (PIB) was studied using dielectric and mechanical relaxation spectroscopies, calorimetry, and RamanExpand
Breast implants: the good, the bad and the ugly. Can nanotechnology improve implants?
The history of implants used in breast reconstruction and augmentation, the most frequently performed plastic surgery today, is reviewed to contribute to a better understanding of the controversial issues and motivate material scientists and medical doctors to work together to develop alternatives based on new nanotechnology.

Carbocationic Polymerization of Isoprene Co-initiated by B (C6f5) 3: an Alternative Route Toward Natural Rubber Polymer Analogues?
The cationic polymerization of isoprene using the 1-(4-methoxyphenyl)ethanol (1)/B(C6F5)3 initiating system in solution (dichloromethane or α,α,α-trifluorotoluene) and in aqueous media (suspension,Expand
Drug-eluting stent coatings.
This paper will demonstrate how drug release profiles were influenced by both the molecular weight of the polyisobutylene core and spraying conditions of the polymer-drug mixture. Expand
Synthesis of Hyperbranched Polyisobutylenes by Inimer-Type Living Polymerization. 1. Investigation of the Effect of Reaction Conditions
Hyperbranched polyisobutylenes (PIBs) have been synthesized by carbocationic copolymerization of an inimer (initiator-monomer, IM) and isobutylene (IB). The IM used was 4-(2-methoxyisopropyl)styreneExpand
