Abstract
The association of polyblock copolymer, poly(siloxane-co-carbonate-co- urethane), in benzene (selective solvent for siloxane component) was s tudied by light scattering, viscometry, and sedimentation methods. Ano malous micellization was observed in a solution in the concentration r ange of 0.02-1.4 g/dl: as the concentration increases, the associates pass through the region of metastable microphase separation and then f orm polymolecular micelles.
