<p>The invention describes oligomeric halogenated diphenyl ether compounds of formula (1), in which Y is the radical of formula (1a); (1b); or (1c); R1 and R2 independently of one another are F, Cl or Br; R3 is the radical of an initiator molecular for the free-radical polymerization; R4 is hydrogen; or C1-C5 alkyl; R5 is the radical of an initiator molecule for the anionic or cationic polymerization; A1 is a fragment from the recombination or from a chain transfer reaction; A2 is the counterion in the ionic polymerization; Q1 is a bivalent radical of formulae: (1d); (1e); (1f); or (1g); m is 1 to 3; n is 1 or 2; p1 is 0, or 1; q1 is 1, 2 or 3; and r1, r2 and r3 independently of one another are 2-20. The oligomeric diphenyl ether compounds according to the invention have excellent antimicrobial properties and are stable to migration.</p> |
