合成了CH_2=CHCOO(CH_2CH_2O)_nCOCH=CH_2大分子交联剂,介绍了一种核磁共振法(~1H NMR)测量该大分子交联剂数均分子量及聚合度的方法,并与气相渗透法(VPO)的结果作了对比。
A method for the determination of the number average molecular weight and the degree of polymerization of the macromolecule crosslinking agent by 1H NMR was introduced. The method of gas phase permeation (VPO) results were compared.
