✦ Synopsis

Osmotic pressure data, obtained from a study of four block copolymers, have been used to calculate second virial coefficients and number average molecular weights. The virial coefficients were determined over a range of temperatures in toluene and cyclohexane. The theta temperatures, entropy of dilution, heat of dilution and the solvent-solute interaction parameters were derived and their behaviour is discussed.

Thermodynamic and contigurational parameters have been derived from data published previously and from some viscosity data presented here. There is evidence to suggest that the block copolymer molecule in dilute solution may be considered as a random coil and therefore that the usual dilute solution

A series of ten block copolymers of poly(isoprene:styrene) have been examined by osmometry over a range of temperatures. Several solvents were used; one was a good solvent for both sequences (toluene), another was a bad solvent for both sequences (methyl t3o-butyl ketone) and another was a preferent

The two-phase structure of polymer blends or block copolymers prepared with polyurethane macroazo initiators and methyl methacrylate or styrene have been studied. The synthesis of these block copolymers was reported in a previous article (Cheikhalard, et al. J Appl Polym Sci 1998, 70, 613-627). One
