Nylon 13,6 was successfully synthesized and its chemical composition, thermal properties, crystal structure, and moisture absorption characterized. Melting temperature and glass transition temperature were determined to be 206 °C and 60 °C, respectively, while the equilibrium melting temperature was determined to be 248 °C. Characterization of the crystallization kinetics showed that nylon 13,6 exhibits...
Polyamide thin-film composite (TFC) membranes were prepared by interfacial polymerization. The purpose is to improve the pervaporation performance of polyamide membranes in separating an aqueous ethanol solution. A novel amine monomer 2,2′-dimethylbenzidine hydrochloride (m-tolidine-H) was reacted with an acyl chloride monomer trimesoyl chloride (TMC) on the surface of a modified polyacrylonitrile...
This work reports that imidazolium-based ionic liquids (ILs) are very efficient solvents and catalysts for the selective synthesis of novel high performance polyamides (PAs) from a new diamine-bisphenol. Direct polycondensation of the diamine-bisphenol was carried out with various dicarboxylic acids by using mixture of: (1) triphenylphosphite (TPP)/N-methylpyrolidone (NMP)/pyridine (Py)/LiCl; and...
A series of polyisobutylene (PIB)-polyamide (PA) multi-block copolymers was synthesized via an amidation reaction to form novel thermoplastic elastomers (TPEs). A two prepolymer approach was taken in which a difunctional primary-amine-terminated polyisobutylene (NH 2 -PIB-NH 2 ) was synthesized as the soft block and a difunctional carboxylic acid-terminated polyamide (HO 2 ...
