✦ Synopsis

Mark-Houwink constants of polystyrene and polyacrylonitrile terpolymers containing acrylonitrile, methyl acrylate, and styrene sulfonic acid or methallyl sulfonic acid as the third comonomer have been calculated from gel permeation chromatography ( GPC) and viscosity data. The data have been used to determine molecular weights of polyacrylonitrile terpolymers.

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 ␣
