摘要
Hydroxypropyl guar gum was prepared based on the reaction of guar gum and propylene oxide.The value of molar substitution was 0.32 and the proportion of two sorts single sugar was 1∶1.67 determined by （）1H-NMR.（）13C-NMR can be used to assume the connection between guar gum and Hydroxypropyl and evaluate the length of hydroxypropyl which was 2～8.
