摘要：

A study has been conducted to determine the effects of added elastomers on the film properties of a linear aromatic polyimide. Polyamic acids have been prepared via reaction of BTDA (3,3 prime ,4, 4 prime -benzophenone tetracarboxylic acid dianhydride) with ODA (4, 4 prime -oxydianiline) and various ATBN (aromatic amine-terminated butadiene acrylonitrile) elastomers. Films were prepared and thermally converted to the corresponding polyimides. Optimum cure conditions for BTDA plus ODA/ATBN films were evaluated. The effect of elastomer concentration on BTDA plus ODA thermal properties, density, tensile properties, morphology and tear resistance were evaluated.
