Abstract
2,2'-Bis(4-(3,4-dicarboxyphenoxy)phenyl)propane dianhydride (6H-BABPA) was synthesized by 4-nitrophthalimide as starting material. Polyetherimides were prepared by conventional two-step method from 6H-BABPA and several diamines. This procedures yielded high molecular-weight polyamic acids and polyetherimides with inherent viscosities of 0.46-2.46, 0.14-1.88 dL/g, respectively. Most of these polymers were soluble in organic solvents such as N-methyl-2-pyrrolidone, N,N- dimethylformamide, N,N-dimethylacetamide, methylene chloride at ambient temperature. The glass transition temperatures of these polymers were in the range of 190-251℃ and the initial decomposition temperatures were over 520℃ under nitrogen.

2,2'-Bis(4-(3,4-dicarboxyphenoxy)phenyl)propane dianhydride (6H-BABPA)를 4- nitrophthalimide를 출발 물질로 하여 합성하였다. 합성된 6H-BABPA와 여러 종류의 디아민과의 단일 중합체를 기존의 two-step방법에 의해 중합하였다. 얻어진 폴리아믹산 중합체와 이를 열 이미드화하여 얻어진 폴리에테르이미드의 고유점도(inherent viscosity)는 0.46-2.46, 0.14-1.88 dL/g의 범위로 각각 얻어졌다. 또한 얻어진 폴리에테르이미드는 상온에서 유기 용매인 N-methyl-2-pyrrolidone, N,N-dimethylformamide, N,N-dimethylacetamide, methylene chloride에 녹았다. 유리전이온도의 범위는 190-251℃ 질소 분위기하에서의 초기 분해온도는 520℃ 이상이었다.
