Abstract: | Emulsion polymerizations of styrene with various phospholipids as emulsifiers were carried out to obtain latices bearing the lipids. Using 1-palmitoyl-2-(4-vinylbenzoyl)-sn-glycero-3-phospho-choline (2a) and 1-[5-(4-vinylphenyl)pentanoyl]-sn-glycero-3-phosphocholine (3) as emulsifiers, latices of narrow size distributions were produced in high yields with a water-soluble initiator, K2S2O8. The lipids were found to be quantitatively immobilized onto the latex surface. With a hydrophobic initiator, 1-palmitoyl-2-[5-(4-vinylphenyl)pentanoyl]-sn-glycero-3-phosphocholine (2c) were bound densely on the latex surface, although the yields were not high. Phospholipase C was found to hydrolyze 2b and 2c attached to the surface. |
