Abstract: The present invention describes the preparation of copolymers grafted by the so-called “grafting from” method, comprising two steps. In the first step, a polymer of a variable type referred to as poly(M1) is reacted with persistent free radicals of the type diphenyltrialkylsilyloxymethyl to form a reactive polymer poly(M1)F, containing a variable number F of these groups attached to the chain. F represents the average functionality of the reactive polymers and may be predetermined by controlling the ratio of poly(M1) and the free radical generator or TPES. In the second step, poly(M1)F is dissolved in a monomer M2 and then redissociated by heating to temperatures of 110-130° C. to produce the macroradical poly(M1) and the persistent radicals. The macroradical poly(M1) rapidly initiates polymerization whereas the diphenyltrialkylsilyloxymethyl radical stays temporarily on the sideline of the initiation reaction.
