摘要：

The temperature coefficient of chain dimensions for poly(p-tert-butylstyrene) (PtBS) has been determined from intrinsic viscosity measurements over the temperature range 10.9-65.0-degrees-C in three chemically similar-THETA-solvents. The value of d ln [r2]0/dT = -1.87 (+/-0.3) x 10(-3) K-1 is larger than the value of -1.1 x 10(-3) K-1 previously established for polystyrene (PS). Some comments are also made regarding specific solvent influences on unperturbed chain dimensions, based on available data for PtBS and PS.
