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.
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.

The mutagenic properties of Ethacure 300, Cyanacure and Polacure 740M, all possible substitutes for the industrial carcinogen, 4,4'-methylene bis(2-chloroaniline), have been determined in Salmonella typhimurium strains TA100, TA98, TA1535 and TA1537. These data have been compared with the effects of
