RESEARCH OF OLIGOMERS FOR COLORING POLYMERS
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 9
Abstract
Epoxy polymers stand out among other polymer materials in a number of properties, playing an important role in aerospace, automotive, shipbuilding and other industries. The purpose of the study is to synthesize epoxy resins based on epichlorohydrin with diphenylolpropane and obtain oligomeric dyes based on them. Their widespread use in technology is associated, firstly, with the high manufacturability of epoxy resins, and secondly, with a unique combination of performance characteristics of their curing products. The optimal conditions for the synthesis of epoxy oligomers have been determined. The structure of the obtained epoxy oligomers was determined by IR spectroscopy and the contents of epoxy and hydroxyl groups in the oligomer were calculated. Dyes containing carboxyl and N-arylsulfonylamide groups capable of quantitatively reacting with the epoxy groups of oligomers were selected
