Block copolymers containing them (orthoesters) and poly bioerodible containing amine groups

摘要

Medicine or orthopedic implants, cosmetic and useful bioerodible poly (ortho ester) contains amine functional group and a hydroxy acid containing α- group as sustained delivery medium for pesticides. Block copolymer, containing bioerodible poly these (ortho ester). These block copolymers, having both hydrophilic and hydrophobic blocks. The form micelles in aqueous solution, they will be suitable for solubilizing or encapsulating water-insoluble substances or hydrophobic. They also, I want to form a bioerodible matrix of sustained release of the active substance.
