These copolymers are denoted by the formulae: <IMAGE> (I) or <IMAGE> (II) P1, P2=vinyl or dienic (p with a value of 1), or polyoxyalkylene, polyester or polyamide (p with a value of 0) polymer block; A=(1) <IMAGE> with R1 denoting, among others, alkyl; (2) <IMAGE> where E, G, J have various meanings; (3) <IMAGE> M, joined to D, having the value <IMAGE> h, i, Q and R having various meanings; D=a single bond or (cyclo)alkylene or arylene group; n=1 to 20. These polymers are iniferters in radical polymerization of vinyl monomers. The macroiniferters (I) and the polyiniferters (II) result, respectively, in triblock copolymers PA-PB-PA and diblock copolymers +545 PA-PB+546 za, z having a value from 2 to 25. |
