And weigh average molecular weight of original oxidized starch and oxidized starch was 7238.70 and 2915.44 respectively, which was determined by high performance liquid chromatogram (HPLC).
高效液相色谱得到初氧化淀粉的重均分子质量为7238·70，氧化淀粉重均分子质量为2915·44。
The results show that the CMC is a high effective surface sizing agent and the mixer of oxidized starch and carboxymethylcellulose in mixed proportion of 2to 1is better in practice.
结果表明，CMC是一种高效的表面施胶剂。生产实际中采用氧化淀粉和CMC按2∶1比例的混合物为好。
