Synthesis of borate ester-grafted carboxylated acrylonitrile butadiene rubber and its use as electron acceptor to dissolve lithium perchlorate

Abstract

The boron atom of borate ester‐grafted carboxylated acrylonitrile butadiene rubber (XNBR‐g‐BE) receives electron pairs from ClO4− anions and facilitates quite well the dissolution of LiClO4 salt in the XNBR‐g‐BE matrix.

Dual‐Responsive Self‐Healable Carboxylated Acrylonitrile Butadiene Rubber Based on Dynamic Diels–Alder “Click Chemistry” and Disulfide Metathesis Reaction

“…The intensity of the absorption bands at 1728 cm −1 (stretching frequency of >CO of free carboxylic groups) and 1698 cm −1 (stretching frequency of >CO of hydrogen‐bonded acid dimer) corresponding to the carboxyl group in XNBR [ 44 ] decreased and a new absorption band emerged at 1667 cm −1 in the spectrum of FXNBR was assigned to >CO stretching of the amide (>CONH 2 ) functionality. [ 45 ] It was observed that the intense absorption band at 2238 cm −1 due to CN stretching in XNBR was not affected in FXNBR after grafting FA on XNBR.…”
