“…[8][9][10][11][12] Detailed discussions of the procedures us_ed in their synthesis and characterization have been given. [8][9][10][11][12] The Mw values of two PBIC samples were determined with a low-angle light-scattering photometer operating at angles from 15 to 150°. The refractive index increment, dn/dc, was determined m tetrahydrofuran.…”
