Cyclobutane-1,2,3,4-tetracarboxylic dianhydride Usage And Synthesis
Chemical Properties

White to light yellow solid


cyclobutane-1,2,3,4-tetracarboxylic dianhydride and diamine monomer are used for preparation a polyimide (PI),

the type of polyimide has excellent electrical characteristics and optical type, with the material prepared the PI film,

in addition to having a higher rate cast visible outside, and can withstand high temperatures thirty-four Baidu. Its performance is very good, is the preparation of a liquid crystal display with an ideal material for the film.

Cyclobutane-1,2,3,4-tetracarboxylic dianhydride uses:

Used in the preparation of biological and pharmacologically active molecules; used in the preparation of photosensitive polyimide materials for high-performance organic thin film transistors; used in the selective crosslinking of polyimide photonic devices.
