✦ Synopsis

This paper reports measurements of the Mark-Houwink constants and the unperturbed molecular parameters of polyepichlorohydrin (in tetrahydrofuran at 25) by the means of gel permeation chromatography with a low angle laser light scattering photometer. The values [:~ =0.80, K = 2.12 x 10 5(dl/g), cr = 1.56, C~ = 4.86,] obtained by this method are in excellent agreement with those [~ = 0.79, K = 2.37 x 10 5(all/g), a = 1.57, C~ = 4.91] obtained by conventional methods.
