Allgemeine Beschreibung

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.

Anwendung

Terephthaloyl chloride was used in the synthesis of liquid crystalline thermosets by thermal cyclotrimerization of dicyanate compounds of ring substituted bis(4-hydroxyphenyl) terepthalates.

Combining polymers with small amounts of stiff carbon-based nanofillers such as graphene or graphene oxide is expected to yield low-density nanocomposites with exceptional mechanical properties. However, such nanocomposites have remained elusive because of incompatibilities between fillers and polymers that are

Poly(ester amide)s are attracting attention because they potentially have excellent thermal and mechanical properties as well as biodegradability. In this study, we synthesized a series of novel poly(ester amide)s by introducing γ-aminobutyric acid (GABA) regularly into polyesters, and investigated their
