General description

1,3-Propanediol bis(4-aminobenzoate) (PBA) is an aromatic diamine. Its crystal structure has been determined by single crystal X-ray diffraction. Its ability to improve the flexibility of electrically conductive adhesives (ECAs) has been studied. Results show that it has a good impact on the electrical, mechanical and thermal properties of the ECAs.
Non-hygroscopic, forms urethanes with good hydrolytic stability, dry heat aging and chemical and environmental resistance.

Application

1,3-Propanediol bis(4-aminobenzoate) (PBA) may be used as a flexibilizer, to prepare a flexible epoxy molding compound (EMC) and also as a chain extender in the synthesis of degradable poly(esterurethane urea) (PEUUR).
A safe, high performance reactant with polyurethane and epoxide prepolymers.

Current scaffolds for the regeneration of anterior cruciate ligament injuries are unable to capture intricate mechanical and chemical gradients present in the natural ligament-bone interface. As a result, stress concentrations can develop at the scaffold-bone interface, leading to poor osseointegration.
