'Reactive Ester Plasticizer For Elastomers'

摘要

Our objective in this initial study was to determine if a reactive ester could provide flexibility and low-temperature properties to a cured elastomer and remain permanent or attached to the polymer after exposure to and extraction by organic fluids. Based on our results in HNBR, our conclusion is that approximately 60-70% of the reactive ester actually was bonded with the polymer. Also, it is quite apparent that the choice and level of peroxide is critical in maximizing the reactivity of the ester to the elastomer. Further studies on other elastomers, such as EPDM and NBR are in progress and will be reported at a later date.
