Liquid rubbers, epoxy-toughening agents

Compatibilized, Segmented Liquid Rubbers as Epoxy-Toughening Agents... [Pg.85]

Aromatic polyesters were investigated to examine their suitability as a toughening agent for epoxy, and found to be effective for a highly crosslinked system. Liquid rubber is less efficient in toughening a highly crosslinked system. lijima and co-workers [132, 133] synthesised a series of polyesters by the reaction of 1,2 ethane diol and aromatic dicarboxylic acid. The latter and the derivatives contained pthalic anhydride. [Pg.262]

Without the addition of a fiexibilizing agent, epoxy resin adhesives have relatively poor characteristics due to the brittle nature of the epoxy matrix.Liquid functionally terminated nitrile rubbers have proved to be an excellent fiexibilizing agent for the epoxy resins. It has been theorized that toughening of the epoxy resin occurs by the formation of a rubbery second phase in the epoxy matrix. With nitrile rubbers over 20% acrylonitrile, order of magnitude increases in fracture toughness of the epoxy matrix have been reported. [Pg.222]
