In this work, we present values for the Mark-Houwink-Sakurada (MHS) and Stockmayer-Fixman (SF) constants for a series of homopolymers of para-substituted styrenes (4-X-styrene; X ϭ OCH 3 , OCH 2 CH 3 , CH 3 , F, Cl, and Br) in THF at room temperature. The respective values of K (in 10 Ϫ5 dL/g) and ␣
