Laser irradiation at 193 nm of gaseous mixture of carbon disulfide and ethene induces co-polymerization of both compounds and affords chemical vapour deposition of C/S/H polymer whose composition indicates reaction between two-three CS2 and one C2H4 molecules. Polymer structure is interpreted on the basis of X-ray photoelectron and FTIR spectra as consisting of >C=S, >C=C<, -CH2-CH2-, (C=C)SnC4-n, -C-(C=S)-S-, -S-(C=S)-S- and C-S-S-C configurations. The gas-phase co-polymerization of carbon disulfide and ethene represents the first example of such reaction between carbon disulfide and common monomer
Laserové ozařování (193 nm) plynné směsi sirouhlíku a etylénu vede ke kopolymeraci obou sloučenin a k chemické deposici C/S/H polymeru z plynné fáze. Složení polymeru nasvědčuje, že reakce probíhá mezi 2-3 molekulami CS2 a jednou molekulou C2H4. Polymerní struktura interpretovaná na základě XPS a IČ spekter ukazuje na existenci >C=S, >C=C<, -CH2-CH2-, (C=C)SnC4-n, -C-(C=S)-S-, -S-(C=S)-S- a C-S-S-C uspořádání. Tato kopolymerace sirouhlíku a etylénu v plynné fázi představuje prvý příklad takové reakce mezi sirouhlíkem a monomerem
