Abstract

The present invention relates to statistical amphiphilic branched addition copolymers, methods for their preparation, and their use in the formation of covalently linked capsules wherein the copolymers are able to emulsify and ultimately self-condense to form covalently cross-linked capsules capable of containing active agents.
