Blends of a new thermoplastic in a thermoset epoxy matrix

摘要: Properties of thermoplastic modified epoxy network have been studied. The particularity this work is the use new epoxies whose structure close to final matrix. Blends thermoset (Diglycidyl Ether Bisphenol A/4-4' methylenebis [3-chloro 2,6-diethylaniline]) with a content from 5 40%w realised. Initial miscibility in precursors shows an UCST behaviour maximal value near 130°C for 10%. Due presence tertiary amine and pendant hydroxyl groups on backbone, reactions are faster than neat system but seems not reacted network. blends transparent toughening increase rather low.
