Initiator and process for cationic polymerization

The invention relates to an initiator for the cationic polymerization of electron-rich alpha -olefins comprising an alpha -iodo ether, according to formula (1). Y - O - R - O - CR R - I (1) where Y = R 3Si where R = an aliphatic residue, optionally containing an ether group R and R = independent H o...

description	The invention relates to an initiator for the cationic polymerization of electron-rich alpha -olefins comprising an alpha -iodo ether, according to formula (1). Y - O - R - O - CR R - I (1) where Y = R 3Si where R = an aliphatic residue, optionally containing an ether group R and R = independent H or C1-C4 alkyl R = C1-C4 alkyl. The invention also relates to a process for preparing a polymer with a polydispersity lower than 1.6 by means of the cationic polymerization of electron-rich alpha -olefins by adding a monomer to an initiator described above and polymerizing it and recovering.
