【Abstract】 To measure intrinsic viscosity of infinite dilution of polysyrene and its copolymer,constants K η and K θ are obtained by Mark-Houwink’s and Stockmayer-Fixman’s formulas.The relationship between the constants and the structure and properties of the side group of the polymer has been approached.更多还原
