Abstract

Compounds adapted to making polymerizable, cross linkable vesicles and methods for making these compounds comprising combining a phophatidylcholine derivative with an acid anhydride of a heterocyclic carbon/disulfide to form reaction products which when dispersed in aqueous buffer form vesicles that are readily polymerized by the addition of a reducing agent. The reduced vesicles form polymerized, highly cross-linked, vesicles which have a much greater stability and longer shelf life.
