The synthesis, and dilute solution behavior of poly(2,4‐dimethylphenyl methacrylate) (2,4DMP), poly(2,5‐dimethylphenyl methacrylate) (2,5DMP), and poly(3,5‐dimethylphenyl methacrylate) (3,5DMP) is described. Comparison is made with results reported for other bulky side chain polymers. The Kuhn‐Mark‐Houwink‐Sakurada (KMHS) relationships were established. The unperturbed dimensions 〈 r 2 〉 ½ 0, the rigidity factor σ, the characteristic ratio C ∞ , and the thermodynamic parameters were determined, using the Stockmayer‐Fixman equation, from viscometric data in good solvents. The high rigidity observed for these polymers is explained assuming that these polymers behave as kinked‐chains.
