Abstract
The paper deals with the synthesis of compounds based on standard epoxy resin/ modified epoxy resin with different molar ratios of glycols and with the characterization of cured products to investigate the influence of the addition of various amounts of modified resin on the compound flexibility as compared to standard epoxy resin. Modification of epoxy resins with glycols results in a wide range of specific properties superior to neat epoxy resin. These properties are highlighted by characterizing the products obtained using various types of glycols and different standard resin/ modified resin weight ratios by physical- mechanical analyses and Dynamic Mechanical Analyses (DMA). Keywords: glycol-modified epoxy resins, glass transition, dynamical properties and mechanical properties
