Title (EN) CYANATE ESTER RESIN COMPOSITION CONTAINING AN EPOXY/AROMATIC ADDUCT
(FR) COMPOSITION DE RESINE A ESTERS DE CYANATE RENFERMANT UN PRODUIT D'ADDITION EPOXYDIQUE/AROMATIQUE
Abstract:
(EN) The present invention generally relates to a thermosettable cyanate ester resin composition which contains a fortifier that is the reaction product of an epoxy and an aromatic reactant selected from an aromatic amine and an aromatic amide. Thermoset cyanate ester resin compositions of the present invention have improved flexural strength and/or flexural modulus. The compositions of the present invention may be used to prepare circuit boards or molded parts.
(FR) L'invention se rapporte d'une manière générale à une composition de résine à esters de cyanate thermodurcissable renfermant un agent renforçateur qui est le produit de la réaction d'un époxyde et d'un réactant aromatique sélectionné parmi une amine aromatique et un amide aromatique. Les compositions de résine à esters de cyanate thermodurcies de la présente invention possèdent une résistance à la flexion et/ou un module de flexion améliorés. On peut utiliser ces compositions pour la production de plaquettes de circuits imprimés ou de composants moulés.
