Isophthaloyl dichloride Usage And Synthesis

Chemical Properties

white crystalline mass

Uses

Intermediate, dyes, synthetic fibers, resins, films, protective coatings, laboratory reagent.

Uses

Isophthaloyl dichloride is used in a variety of performance polymers and fibers, where it impacts flame resistance, temperature stability, chemical resistance, and flexibility. In addition, it is an effective stabilizer for urethane prepolymers due to its ability to scavenge water. Also used in aromatic fiber raw materials.

General Description

Isopthaloyl chloride acts as a crosslinking agent in various polymerization reactions.
