摘要： The invention relates to novel materials based on biodegradable polyamino acids that are useful for vectorizing active principle(s)(AP). The aim of the invention is to supply a new polymeric raw material that is used for vectorizing AP and optimally fulfills all requirements concerning biocompatibility, biodegradability, the ability to be easily associated with numerous active principles or solubilize the active principles and to release the active principles in vivo. Such polymers can also be readily and economically transformed into particles vectorizing active principles according to the grafting rate of the hydrophobic groups, said particles being able to form stable aqueous colloidal suspensions.
