Synthesis of Poly(N-acylethylenimine)s.

Using methyl 4-nitrobenzenesulfonate as an initiator and o-dichlorobenzene as a solvent, decenyl (D) and heptyl (H) oxazolines monomers in ratio of 20/80 were copolymerized. Substitute oxazolines via ring opening copolymerization resulted in a random OH copolymer with a degree of polymerization of 100. Solution copolymerization as living cationic system is very sensitive to the presence of any trace of water in reaction vessel. Narrow molecular weight distribution was obtain by using purified chemical agents and well controlled copolymerization reaction. The copolymer can be considered as the poly(N-acylethylenimine)s with allyl pendant groups randomly attached to the far end of their polymethylene side chains. Chemical structure and moleculare wieght of the polymer were characterized by NMR and GPC.
