Abstract (en)

[origin: WO2006125892A1] The invention concerns a controlled architecture copolymer comprising at least one block A obtained by polymerizing a mixture of ethylenically unsaturated monomers (A<SUB>0</SUB>) not including vinyl phosphonate monomers and at least one block B obtained by polymerizing a mixture of ethylenically unsaturated monomers (B<SUB>0</SUB>) including at least 50 mole % of at least one monomer B<SUB>1</SUB> bearing at least one vinyl phosphonate function. The invention also concerns a method for synthesizing a controlled architecture copolymer comprising at least one block A obtained by polymerizing a mixture of ethylenically unsaturated monomers (A<SUB>0</SUB>) not including monomers with vinyl phosphonate monomers and at least one block B obtained by polymerizing a mixture of ethylenically unsaturated monomers (B<SUB>0</SUB>) including at least 50 mole % of at least one monomer B<SUB>1</SUB> bearing at least one vinyl phosphonate function. The invention further concerns the use of the copolymer as anti-scaling agent, as dispersant, as emulsifier or surface modifier.
