摘要：
The solubilization of polyisobutylene by micelles of polystyrene-b-poly(ethylene/propylene) block copolymers in several ketones (dipropylketone, 5-methyl-2-hexanone, methyl isobutyl ketone, diethyl ketone, and methyl propyl ketone) has been studied. The maximum polyisobutylene concentration solubilized in the different copolymer/solvent systems has been determined by laser light scattering. The solubility curves have been found to be linear and dependent on the polyisobutylene molar mass,the chemical composition of the diblock copolymer, and the solvent. The logarithm of the maximum amount of homopolymer solubilized by gram of copolymer varies linearly with the logarithm of the homopolymer molar mass, and this variation is hardly dependent on the chemical composition of the copolymer and the precipitant character of the solvent.
