    摘要: Bioerodible poly(ortho esters) useful as orthopedic implants or vehicles for the sustained delivery of pharmaceutical, cosmetic and agricultural agents from dioxane-based di(ketene acetals). Block copolymers contain these bioerodible poly(ortho esters). These block copolymers have both hydrophilic and hydrophobic blocks. They form micelles in aqueous solution, making them suitable for encapsulation or solubilization of hydrophobic or water-insoluble materials; and they also form bioerodible matrices for the sustained release of active agents.

    摘要: Polymers useful as orthopedic implants or vehicles for the sustained delivery of pharmaceutical, cosmetic and agricultural agents are prepared in such a manner that the rate and degree to which they are hydrolyzed can be controlled without addition of exogenous acid. This control results from the incorporation of esters of short-chain .alpha.-hydroxy acids such as esters of glycolic acid, lactic acid or glycolic-co-lactic acid copolymer into the polymer chain and variation of the amount of these esters relative to the polymer as a whole.
