摘要：

Epoxy matrices with a tunable matrix (vitrimers) are synthesized for the first time by curing a cycloaliphatic epoxy resin3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylatein the presence of 4-methylhexahydrophthalic anhydride as a crosslinking agent and zinc acetylacetonate as an interchain exchange catalyst. It is shown that at room temperature the epoxy vitrimers behave like ordinary thermosets but are capable of reshaping and welding when heated.
