As mentioned before, in the world because of this kind of materials R & D has a strong military background, so the European Paris Commission (COCOM) from the beginning has listed it as strategic materials strict implementation of the embargo on China and other socialist countries. China's development of national defense industry and civil high-tech, of course, is in urgent need of this new class of materials. Control is not, break the blockade and embargo, countries have to in the relevant national planning research project implementation of the stand on one's own research and development. This task has been respectively by the Research Academy of Sciences and the relevant ministries and institutions of higher learning to bear.

Using polyimide as an example, USA Dupont company, in 1960 to start a commercially available, the academy also completed laboratory research and development in the mid 60's, and the factory manufactured products in small quantities, satisfy the need of national defense. But so far has not formed a scale of industrialization such as Dupont company. Of course other varieties are also similar, so far domestic above all varieties from the industry perspective, the largest is the PPS, Sichuan China has built 1000t/y device. According to the talk, 5000t/y scale will start.
