Polyimide(PI) film etched by electron beam(EB) to produce PI micron-hole separation membrane combined with the methods of masks and oxygenation corrosion was studied in this paper.

Using TG-DTG,DSC and IR techniques,the non-isothermal decomposition kinetics of a new polyimide(PI) which is synthesized by 3,3′,4,4′-benzophenone tetracarboxylic dianhydride(BTDA) and 4,4′-(1,3-phenylenedioxy)-dianiline(CAS: 2479-461),were studied.

As a kind of polymer material, polyimide(PI) holds a favorable complanation property and is easy to become ash in the oxygen.

Recent progress of the polyamide/mineral nano-compsites was introduced.

A kind of porous polyamide is prepared by adding the pore forming additive.

There are mainly four kinds of methods to synthesize the soluble polyamides by molecule designs,i.

Overview on the soluble and transparent polyimides

The progress of polyimides in the low thermal expansion coefficient and it′s manufactures and applications were summarized.

Condensation type polyimides were prepared by using DDBT (dimethyl 3,7 diaminobenzathioplene 5,5 dioxide) and several dianhydrdes such as pyromellitic dianhydride (PMDA), 3,3′,4,4′ biphenyltetracaboxylic dianhybride (BPDA), 2,2′ bis 3,4 [dicarboxyphenyl] hexafluorepropane dianhydride (6FDA) and 3,3′,4,4′ diphenylsulfone tetracaboxylic dianhydride (DSDA).
