摘要
测定一组未分级的SAN试样的重均分子量M_W、特性粘数[η]和分子量多分散度D,然后对马克-郝文克方程[η]=KM~α中的K作多分散改正,定出SAN在丁酮溶剂中,30℃的K=3.02×10^(-4),α=0.65。
The weight-average molecular weight Mw,instrinsic viscosity [η] and polydispersity D of molecular weight of unfractionate SAN samples have been determined.$The K in Mark-Houwink equation[η]=KM~α is then corrected. Using polydispersity, and K=3.02×10^(-4), α=0.65 for SAN have been determined in butanone at 30℃.
