ABSTRACT:
The invention relates to a method of preparing a composition of living polymers comprising a non-photoinitiated radical polymerization step using a composition consisting of: at least one ethylenically unsaturated monomer, preferably a methacrylic monomer, at least one disulphide compound having formula (II), i.e. Z1—C(═S)—S—S—C(═S)—Z2; and at least one thermally-activate free radical source which is different from the formula (II) compound.
