FIELD: polymerization processes.
SUBSTANCE: polymer containing at least one boronate substituent or its precursor is prepared by controlled living radical polymerization of monomers in presence of living chain growth control agent, in particular sulfur-containing compound having S-C(S)- bond, said monomers being represented by (i) at least one monomer having at least one boronate substituent or its precursor and selected from group consisting of acryloylbenzeneboronic acid, methacryloylbenzeneboronic acid, vinyl-4-benzeneboronic acid, 3-acrylamidophenylboronic acid, 3-methacrylamidophenylboronic acid, individually or in mixture, or in salt form, and (ii) at least having no boronate substituents nor their precursors. Also described is associate containing above-defined polymer with at least one compound ligand having at least one group capable of forming complex with the polymer containing at least one boronate substituent or its precursor.
EFFECT: narrowed molecular mass distribution and uniformity along the polymer chain.
