STUDIES ON THE SYNTHESIS AND PROPERTIES OF NOVEL PHOSPHOLIPID ANALOGOUS POLYMERS

Two kinds of phospholipid analogous compounds, methacrylate monomers ( 4a-b) and acrylamide monomers (5a-b), were prepared and polymerized wi th a radical initiator in water at room temperature. The viscosity beh avior of these charged polymers were investigated in the presence or a bsence of inorganic salts, and the found inherent viscosity [eta] of a mide polymer (poly7a) is higher than those of ester polymers (poly6a1 and poly6b). On the other hand, the radical copolymerization of monome r 5b with acrylamide (AAm) was also carried out in water. Based on the x-ray analyses, it is proposed that some of the obtained polymers sho w ordered bilayer structures in condensed phase. Furthermore, the ther mal properties were studied by DSC and TG-DTA measurements. (C) 1996 J ohn Wiley & Sons, Inc.
