Polyisobutylene based biomedical materials: imparting new properties and functions

聚异丁烯（PIB）是一种高性能合成弹性体，具有高弹性、化学稳定性和不透水/不透气等优点。它目前被用于许多商业产品，包括轮胎的内胎，篮球和足球等运动器材的膀胱，润滑油和发动机燃料，密封剂，甚至口香糖。尽管有这些不同的应用，目前全球80%的PIB生产是针对轮胎市场的。由于燃料成本上升和环境问题，汽车的持续长期增长不确定，为了确保PIB市场的持续增长，探索和扩大PIB在新领域的应用至关重要。生物医学材料和设备市场尤其具有吸引力，因为它们预计将有强劲的长期增长

Polyisobutylene (PIB) is a high performance synthetic elastomer possessing attractive properties including high eleasticity, chemical stability, and water/gas impermeability. It is currently used in many commercial products including the inner tubes of tires, the bladders of sporting equipment such as basketballs and soccer balls, lubricating oils and motor fuels, sealants, and even chewing gum. Despite these diverse applications, currently 80% of the global PIB production is directed towards the tire market. With the continued long term growth of the automobile uncertain due to rising fuel costs and environmental concerns, in order to ensure continued growth of the PIB market, it is critical to explore and expand the applications of PIB in new areas. The biomedical materials and devices markets are particularly attractive as they are projected to have strong long
