Preparation of New Polymer from Acetone and Sulfur Chloride

Abstract

When a chloroform solution of S₂Cl₂ was brought into contact with acetone, vigorous reaction was observed to give a new type of polymer, which showed mp. 56-57°C, sulfur content 60.75%, 1710cm^-1, 1360cm^-1, 500cm^-1, 480cm^-1 in infrared spectrum, 1.62ppm (CH₃, group) 2.60, 2.73ppm (CH₂, group) in NMR spectrum, in CDCl₃ solution. Its structure was suggested as-(Sx-C (CH ₃) ₂-O-)-(Sx-CH₂-CO-CH₂)-(Sx'-CH₂-CO-CH₂). Molecular weight of this polymer determined by vapour pressure osmometer in chloroform solution was 2360.
