采用凝胶色谱法,测定分子量3000以下的聚异丁烯和聚乙烯醋酸乙烯酯的分子量分布.色谱柱的标定是利用宽分布标样,以自编的Fortran程序在计算机上计算的.
Gel chromatography was used to determine the molecular weight distribution of polyisobutylene and polyethylene vinyl acetate with a molecular weight of 3000. The calibration of the column was calculated on a computer using a self-compiled Fortran program using a wide range of standards.
