DILUTE-SOLUTION PROPERTIES OF POLY(P-T-BUTYLSTYRENE)

The dilute solution properties of poly(p-t-butylstyrene) (PtBS) in cyc lohexane, a good solvent, and 2-octanol, a theta solvent, are reported . The polymers are narrow-molecular-weight-distribution samples produc ed by an anionic polymerization process and span more than two orders of magnitude of molecular weight. The techniques used to study solutio ns of PtBS include static and dynamic light scattering, solution visco metry, and size exclusion chromatography. The results are compared wit h those obtained from other polymer/solvent systems and with predictio ns from various theories.
