GAMMA-BENZYL-L-GLUTAMATE GRAFT-COPOLYMERS OF CELLULOSE AND POLY(ARYLENE ETHER SULFONE)

Macroinitiators with primary amino substituents were synthesized by several techniques. Experimental results show that if reaction times between 24 and 48 h are utilized, high grafting efficiencies (>80%) are obtained. The conformation of the polypeptide chain was evaluated by NMR and infrared spectroscopy. Polypeptides grafted to certain polymers appeared to adopt the expected conformation for the chain length predicted, i.e., a progression from random coil (13 amino acids).
