1. A membrane active polyamine formed by the process comprising:
- polymerizing via chain polymerization a plurality of input first monomers each containing a pendent protected amine, a plurality of input second monomers each containing a first hydrophobic pendent group having two to six carbon atoms, and a plurality of input third monomers each containing a second hydrophobic pendent group having twelve to twenty-two carbon atoms, thereby forming an amphipathic random heteropolymer and deprotecting the protected amines thereby forming the membrane active polyamine, wherein the ratio of input monomers is selected such that the membrane active polyamine contains a ratio of first monomers to second monomers to third monomers is about 6;

Abstract
The present invention is directed to a class of membrane active polymers useful for cellular delivery of compounds. Conjugation of the described membrane active polymers to targeting, anti-opsonization, and anti-aggregation agents provides polymers suitable for in vivo delivery. The use of multiple reversible linkages connecting component parts provides for physiologically responsive activity modulation.
