The solubilization properties of P60E348 (P = Oxypropylene, E = oxyethylene, subscripts = number of repeating units) diblock copolymer micelles containing liquid crystals have been studied by light scattering and UV spectroscopy for mainly dilute solutions from the following viewpoints: (i) the micellar solubilization rate J of a nematic liquid crystal (LC), predominantly pentylcyanobiphenyl, (ii) the amount of solubilized material at saturation, and (iii) the apparent size of the P60E348 micelles containing LC and their intermicellar interaction properties. It was shown, in experiments with solubilization temperature T-s = 50 degreesC, that the rate J is inversely proportional to the copolymer concentration c(p) in the range 2 g L-1 less than or equal to c(p) less than or equal to 10 g L-1 whereas J is constant at higher values of c(p). It was also shown that J increases strongly with an increase in temperature. The micellar hydrodynamic radius R-h was independent of temperature in the range 30 degreesC less than or equal to T less than or equal to 60 degreesC, whereas there was a reduction in the hydrodynamic virial coefficient k(D) and in the thermodynamic second virial coefficient A(2) as T was increased (for T-s = 40 degreesC). To probe the intermicellar interference, the excess scattered intensity was measured as a function of c(p), showing an increasing deviation from linearity, reflecting the transition from a dilute to a concentrated system and the increasing predominance of intermicellar interactions.
