Structure and properties of epoxy composites cured with new organosilicon amines

The results of the curing of bisphenol A-based epoxy oligomers (ED-20 and NPEL-128) with silicon-containing amines (SCAs) synthesized by the interaction between bifunctional alcohols with different molecular masses and γ-aminopropyltriethoxysilane (AGM-9) are reported. It is shown that, in the case of using SCAs, epoxy oligomer is cured more completely and a higher degree of elasticity in the polymer matrix is achieved without using modifiers, which is impossible in the case when polyethylene polyamines are used.
