PROCESS FOR PREPARING A COPOLYMER WITH CONTROLLED ARCHITECTURE, OF TELOMER OR BLOCK COPOLYMER TYPE, OBTAINED FROM VINYL PHOSPHONATE MONOMERS, BY IODINE TRANSFER POLYMERIZATION

摘要

The present invention relates to a process for synthesizing a copolymer having controlled architecture, comprising at least one block A obtained by the ITP polymerization of a mixture of ethylenically unsaturated monomers (A₀), containing no monomers having vinyl phosphonate functions, and at least one block B obtained by polymerizing a mixture of ethylenically un-saturated monomers (B₀) containing at least one monomer B₁ which carries at least one vinyl phosphonate function. The present invention also relates to a process for synthesizing a copolymer having controlled architecture, of the telomer type, comprising at least one chain B obtained by polymerizing a mixture of ethylenically unsaturated monomers (B₀) containing at least one monomer B₁ which carries at least one vinyl phosphonate function, by ITP polymerization; to the telomer obtainable; and to the uses thereof.
