“…During the summer of 1979, attempts were made at this laboratory to develop a gas-chromatographic procedure for analysis of vinylidene chloride. In the meantime Foerst (5) reported that vinylidene chloride can be analyzed by gas chromatography by using Durapak OPN as an analytical column.…”

A gas-chromatographic analysis of vinylidene chloride (1,1-dichloroethylene) is presented. Vinylidene chloride was sampled by adsorbing on activated carbon. It was desorbed with carbon disulfide. The desorption efficiency was 97.2 +/- 1.05 (mean +/- standard error). The analytical column was packed with 10% Apiezon L on acid-washed Chromosorb-P. The analysis was conducted on a gas chromatograph equipped with a flame ionization detector.

Vinylidene chloride is a versatile monomer used primarily for making vinylidene chloride copolymers. These copolymers are mostly used in food packaging to provide a good barrier to mass transport. Most applications rely on the low permeation of oxygen, carbon dioxide, and water vapor. However, the polymers have also been shown to have good barrier to flavors and aromas. These copolymers are available in three formats. First, resin for extrusion into film or sheet represents the largest segment. Typically, coextrusion is used because only a small amount of vinylidene chloride is necessary for the barrier and other polymers can provide the strength. Second, resin is used for solution applications. A thin layer is coated onto a substrate. Third, latex is used for coating. The coatings from solution or latex dry clear. Vinylidene chloride homopolymer does not have commercial application because its melting temperature is too high to extrude without degradation, and it does not dissolve in a suitable solvent for coating.
