WebProton NMR was found to be useful in identifying lots that have an abnormal amount of CTBN protons. One such lot exhibited a phase separation of a polybutadiene impurity. Carbon-13 NMR was found to be capable of determining nitrile content directly. Carbon-13 NMR had a relative standard deviation of 8.3% and a proton NMR of 3.9%. WebOct 10, 2011 · Cyanoacrylate fuming is one of the most common techniques employed for the detection of latent fingermarks on non-porous surfaces such as plastic and glass. The technique is generally applied by exposing items of interest to the vapours generated by heating a suitable quantity of commercial cyanoacrylate adhesive.

WebMar 1, 2024 · PBCA is a homopolymer composed of n-butyl-2-cyanoacrylate (BCA) monomer units. The monomer is successfully applied as a biomedical tissue adhesive due to the fast polymerization mechanism [14]. However, the lack of commercially available PBCA bears a challenge for the production of PBCA-based drug delivery systems.
