General description
Terephthaloyl chloride is a highly reactive acid chloride derived from terephthalic acid. It is used as a cross-linking agent in polymer synthesis. Terephthaloyl chloride undergoes condensation reaction with difunctional α,ω-diaminopolystyrene to yield chain-extended polystyrene containing amide bonds along the polymer backbone. It undergoes interfacial reaction with bovine serum albumin to form thin cross-linked films.
Application
Terephthaloyl chloride was used in the synthesis of liquid crystalline thermosets by thermal cyclotrimerization of dicyanate compounds of ring substituted bis(4-hydroxyphenyl) terepthalates.
