Popis:	The telomerization of 2-(dimethylamino)ethyl methacrylate (DMAEMA) with 2-mercaptoethanol in acetonitrile shows that the telogen can react with the monomer by nucleophilic addition. It is to say that the tertiary amino group leads to mucleophilic addition rather than telomerization. The oligomers thus obtained were functionalized with 1-(isopropenylphenyl)-1,1-dimethylmethyl isocyanate (TMI) in anhydrous toluene to afford macromonomers. These macromonomers were copolymerized with styrene and the r 1 , r 2 ratio was determined according to Jaacks and Macret's methods. It was thereby demonstrated that the r 1 value for this type of monomer is close to zero.
