摘要:

以4-氯代酞酰亚胺和双酚F为原料,在N,N′-二甲基乙酰胺溶剂中,经水解、酸化、脱水,合成了一种新型的双酚F型二酐(BPFDA)单体,并用1H NMR和IR测试方法确认了其结构。 采用传统的一步法,用N,N′-二甲基乙酰胺作溶剂,BPFDA分别与4,4′-二氨基二苯醚(ODA)和4,4′-二氨基二苯甲烷(MDA)聚合,得到聚酰胺酸,并进一步热亚胺化得到聚酰亚胺薄膜,并对其进行了表征。 结果表明,BPFDA/ODA薄膜和BPFDA/MDA薄膜的玻璃化转变温度分别为200和204 ℃; 热失重分析表明,质量损失5%的温度分别为506.50和459.10 ℃;其拉伸强度分别为110和100 MPa。

Abstract:

A novel bisphenol F-type dianhydride(BPFDA) monomer was synthesized using 4-chlorophthalimide through hydration, acidification, and dehydration. Its structure was determined with 1H NMR and IR. Two types of polyimide films were prepared with the dianhydride and 4,4′-diaminodiphenyl ether(ODA) or 4,4′-methylene dianiline(MDA) via conventional one-step method in N,N′-dimethylacetamide. The obtained polyamic acid was then further imidized into polyimide films and characterized. Results show that the glass-transition temperatures of the polyimide films were 200 and 204 ℃;the temperatures of 5% mass loss were 506.50 and 459.10 ℃; and the tensile strength of the films were 110 and 100 MPa, respectively.

Key words: BPFDA, Polyimide, Thermal property, Mechanical properties.
