Rosinamideimides modified with polyarylsiloxanes containing phenyl ,tolyl, pyridinyl groups were synthesized in the presence of triphenylphosphite catalyst by the direct polycondensation reaction of rosin-maleic anhydride adduct(RMA) with amino group terminated polyarylsiloxanes, Their thermal stabilities were increased with introdicing phenyl group in polyary1siloxane. Their adhension properties were measured by the peel test and also increased with introducing phenyl group.
