The Adsorption Behavior of Polystyrene-Poly (Methyl Methacrylate) Mixtures Containing Block Copolymers
The preparation and characterization of block copolymers has been actively pursued in recent years (l). Although such copolymers have been recognized as unique interface active species, their behavior at solid/liquid interfaces has received relatively little attention. Accordingly, a study has been made of the adsorption behavior of samples containing S/MMA block copolymers of the AB type. The styrene/methyl methacrylate (S/MMA) system was chosen because the adsorption behavior of S and MMA homopolymers has been studied, both as individual polymers and as mixtures (2). Since the S/MMA block copolymer synthesis procedure consistently yielded a mixture of S and MMA homopolymer plus S/MMA block copolymer, all measurements thus far have been confined to such mixtures.
