The dilute‐solution properties of six poly(tetrahydro‐4 H ‐pyranyl‐2‐methacrylate) (PTHPM) fractions covering the molecular weight ( M w ) range 4.8 × 10 4 to 8.4 × 10 5 ( M w / M n = 1.2–1.4) were studied in tetrahydrofuran, a good solvent, and in isobutanol, a θ solvent a t 30.5°C as determined by light scattering from the A 2 vs. T plot. The unperturbed dimensions were calculated from a low‐angle laser light‐scattering and intrinsic‐viscosity data. The results indicate that PTHPM is less extended chain than poly(cyclohexyl methacrylate) (PCyM). The higher flexibility of PTHPM parallels the lower T , (57°C) of this polymer relative to PCyM (66°C).
