对聚(2，b-二甲基-1，苯氧基)的15个级分的甲苯溶液进行了光散射和渗透测量，并在25℃下测量了粘度。甲苯(15个馏分)、氯苯(7个馏分)和氯仿(8个馏分)。FI值在26,500-415,000之间，[T]在26-175ml./g之间。得到如下Mark-Houwink关系式：[71](ml./g)=2.85x.fiv0。68‘O’‘(甲苯)=3.78 x IVO。66‘0.02(氯苯)
Light-scattering and osmotic measurements have been made on toluene solutions of fifteen fractions of poly (2, b-dimethyl-1, Cphenylene oxide), and viscosity measurements at 25OC. in toluene (15 fractions), chlorobenzene (7 fractions), and chloroform (8 fractions). The fi, values range between 26,500 and 415,000, and [T]] between 26 and 175 ml./g. The following Mark-Houwink relationships are obtained:[71](ml./g.)= 2.85 x. fiv0. 68'O.''(toluene)= 3.78 x ivo. 66'0.02 (chlorobenzene)
