Comparative Study of Composite Materials Based on Di[1-(2-Glycidyloxyethoxy) Ethyl] Ether of Diphenylolpropane and Diglycidyl Ether of Diphenylolpropane
Abstract: A comparative study of polymer composites based on an epoxidized derivative of 2-(vinyloxy)-ethoxymethyloxirane (product ES-6) and diglycidyl ether of diphenylolpropane (resin Epikote-828) was carried out over a wide temperature range. It has been shown that at temperatures below 260 K, the strength of the vinylox-based epoxypolymer exceeds the strength of the polymer based on Epikote-828. A similar pattern is observed for the modulus of elasticity. As for the deformation at break, it remains practically unchanged in the studied temperature range (150–300 K) for Epikote-828 resin and decreases almost monotonously with decreasing test temperature for ES-6 resin. Dynamic mechanical spectrometry has revealed a number of relaxation transitions associated with the cooperative movement of macromolecule segments and smaller sections of the molecular chain. Due to the observed combination of tensile strength and tensile strain parameters in a very wide temperature range below room temperature, the composition based on 2-(vinyloxy)-ethoxymethyloxirane surpasses epoxypolymers based on the traditional Epikote-828 resin in terms of the amount of fracture work. This makes it possible to obtain very frost-resistant materials based on ES-6 resin.
