| Abstract: | A method for determining hydroxyl value of epoxy-containing polyester,namely acetyl chloride method is introduced. The hydroxyl value of epoxy-containing polyester was determined by analyzing acetification principle and using acetyl chloride as acetifier and methylene chloride as solvent.The results show that there is not coagulation in experiments,and the deviation is small. |
