The purity of the cyanoacrylate monomers was estimated by gas- chromatographic technique. Some of the impurities, like diglyme, cyanoacetates, were identified by noting the retention volumes. A plot of the retention volumes vs. number of carbons in the alkyl part of the cyanoacrylates was found to be linear however, the use of temperature programming to obviate the broadening of the peaks for compounds having higher retention volumes was not successful, due to the shifting of the base line with increase in temperature.
