Modification Study on Quantitative Methods of Epoxy Functional Groups in Epoxy Chain Extenders
For lack of a unified standard for the determination of epoxy equivalent in epoxy type chain extenders on the current market,we conducted an in-depth study exploring the determination methods of epoxy equivalent in epoxy type chain extenders from different manufacturers based on the current national standard GB/T 4612-2008 Plastics-Determination of Epoxy Equivalent in Epoxy Compounds.We discussed and optimized key steps such as the dosage of different reagents in its determination methods,proposing a suitable determination method for epoxy equivalent in epoxy type chain extenders.This proposed method is easy to operate,fast in analysis,and has low requirements for sample solutions,making it very suitable for quality control of products in factories,workshops,and other production processes.
