Method of producing new polysulphones with general formula 1, where R represents radical alkyl C1-C10, m=1,2,3..., and n is large or equal 2, is characterised in that acrylate alkyl, in which substituent in ester group, with the above value, in molar quantity 1-85% in the initial mixture, is submitted free-borne copolymerisation reaction with sulphur dioxide in temperature of 195-333 K, then the created compound with formula 1 is extracted from the reaction mixture by familiar methods.<IMAGE>
