| abstract |
The invention relates to a process comprising a step of polymerization or copolymerization of at least one monomer which can be polymerized or copolymerized by the radical route in the presence of a stable free radical and an initiator of formula R 1 ―O ― O ― R 2 in which R 1 and R 2 , which may be identical or different, represent an alkyl, aryl, alkylaryl or aralkyl radical comprising, for example, from 1 to 20 carbon atoms.n n n The process is fast, allows the initiator to play its role more efficiently, and leads to polymers or copolymers having a low yellow index. |
