Studies in the molecular weight distribution of epoxide resins. II. Chain branching in epoxide resins

摘要

AbstractThe extent of side chain branching in epoxide resins based on bisphenol A has been determined by nuclear magnetic resonance spectrometry. The results indicate that for the resins studied in this paper, the extent of branching is very small. The number of branch points varies between 0.09 to 0.06 per molecule for epoxide resins whose number‐average molecular weight lies between 1500 and 400
