Two carboxyl-terminated butadiene acrylonitrile (CTBN) copolymers, named Lan-1 and Lan-2, were synthesized by solution radical polymerization. They had similar physical properties with the commercial sample Hycar1300×13, but had higher viscosity. The results of 1H NMR and 13C NMR revealed that Hycar1300×13 had more branched chains and more acrylonitrile-1,4 butadiene bonded units, but had lower acrylonitrile–acrylonitrile and acrylonitrile-1,2 butadiene bonded units, compared with Lan-1 and Lan-2. This improved the flexibility of the molecular chains of Hycar1300×13, and correspondingly decreased its viscosity.
