| Abstract: | The possibility was shown of decreasing the temperature of softening of ED-8 brand high-molecular-weight solid epoxy oligomer by means of creation of mixtures with DER-332, DER-330, ED-22, and ED-20 low-viscosity epoxy oligomers. It was shown that the softening temperature of epoxy oligomers and their mixtures can be controlled by directional variation of molecular weight, molecular-weight distribution, and content of the low-molecular-weight fraction. |
