Synthesis of Polymers Containing Stable ARs

Polyvinylacetate with ARs was obtained by the reaction with radical III (R=COOH) [86]. Macromolecules of modified polyvinylacetate contain from 1 to 10 ARs. 

Polyacrylates, polymethylacrylates and polymethylmethacrylate with ARs are synthesised by reaction of the copolymer containing chloranhydride groups with a radical IV (R=OH) [87]  

Synthesis of spin-labelled polystyrene has been carried out by the reaction of the polymer containing chlormethyl groups with radical IV (R=OH) [88, 89]  

Polyethylene films containing carbonylhydrazide groups were treated by radical IV (R = -N=C=S) [91]. The spin-labelled polyethylene was obtained hy the following reaction  

Synthesis of the spin-labelled copolymer of styrene with maleic anhydride has been carried out on heating a solution of the copolymer and radical IV (R=NH2) in
