Summary: The laser irradiation at 193 nm of a gaseous mixture of carbon disulfide and ethene induces the copolymerization of both compounds and affords the chemical vapour deposition of a C/S/H polymer, the composition of which indicates the reaction between two to three CS 2 molecules and one C 2 H 4 molecule. Polymer structure is interpreted on the basis of X‐ray photoelectron and FT‐IR spectra as consisting of >CS, >CC<, CH 2 CH 2 , (CC)S n C 4 − n , C(CS)S, S(CS)S, and CSSC configurations. The gas‐phase copolymerization of carbon disulfide and ethene represents the first example of such a reaction between carbon disulfide and a common monomer.Scheme showing the expected reaction of excited CS 2 molecules with other CS 2 molecules to form dimers, which then react with another CS 2 molecule or add to ethene.
