Anhydride polymers that release active or activatable agent(s) have pre-selected properties such as molecular weight, flexibility, hardness, adhesiveness, and other valuable properties. The polymers are suitable for use in compositions, formulations, coatings, devices, and the like that benefit from the controlled release of an agent(s) over a period of time. The polymers are prepared by a process involving various alternative and sequential steps that allow the design a priori of products with specific characteristics. The polymers are suitable as delivery systems, either by themselves, as compositions, formulations or devices.
无水酐聚合物释放活性或可激活的药剂,具有预选特性,如分子量、柔韧性、硬度、粘附性等其他有价值的特性。这些聚合物适用于在一段时间内控制释放药剂的组合物、配方、涂层、设备等,这些产品受益于药剂的控制释放。这些聚合物是通过涉及各种替代和连续步骤的过程制备的,这些步骤允许事先设计具有特定特性的产品。这些聚合物适合作为传递系统,可以单独使用,也可以作为组合物、配方或设备。
