New polyamino acids having grafted alpha-tocopherol moieties, useful as biodegradable, biocompatible carriers for active agents, e.g. drugs, nutrients, cosmetic agents or plant protectants

摘要

Polyamino acids (I) comprising aspartic and/or glutamic units, where at least some of the units carry grafts containing at least one alpha-tocopherol moiety, are new.
