Comonomers for Bismaleimides: o,o'-Diallylbisphenols

Abstract

A series of new diallylethers has been synthesized from selected bisphe nols. Several of these bisphenols, notably 2,2-bis(4-hydroxyphenyl)hexafluoropropane, bis(4-hydroxyphenyl)-p-diisopropylbenzene, bis(4-hydroxyphenyl)-m-diisopropylben zene and 9,9'-bis(4-hydroxyphenyl)fluorene, were converted to the corresponding o,o' diallylbisphenols. These new materials were thermally copolymerized with bismaleimides to give tough, high T_g copolymer networks .
