Abstract (en)

[origin: WO2007051858A2] The invention relates to novel comb polymers supporting, on a carbon backbone, poly-C<SUB>2</SUB>-C<SUB>4</SUB>-alkylene ether side chains A and functional groups B, which exist in the form of anionic groups at a pH > 12, and to the salts of comb polymers of this type. The invention also relates to the use of these comb polymers as additives in preparations containing a mineral binder. The polyalkylene ether side chains A have the following formula *-U-(C(O))<SUB>k</SUB>-X-(Alk-O)<SUB>n</SUB>-Y-Z A, wherein: * represents the binding site to the carbon backbone of the comb polymer; U represents a chemical bond or an alkylene group with 1 to 8 C atoms; X represents oxygen or a group NR; k represents 0 or 1; n represents an integer whose mean value, with regard to the comb polymer, ranges from 5 to 300; Alk represents C<SUB>2</SUB>-C<SUB>4</SUB> alkylene, Alk being able to be the same or different within the group (Alk-O)<SUB>n</SUB>; Y represents a linear or branched alkylene group with 2 to 8 C atoms, which can support a phenyl ring; Z represents a 5- to 10-membered nitrogen heterocyclic compound that, as ring members, can comprises, in addition to the nitrogen atom and the carbon atoms, 1, 2 or 3 additional heteroatoms selected among oxygen, nitrogen and sulfur, the nitrogen ring members being able to contain a group R', and 1 or 2 carbon ring members can exist in the form of a carbonyl group; R represents hydrogen, C<SUB>1</SUB>-C<SUB>4</SUB> alkyl or Benzyl, and; R' represents hydrogen, C<SUB>1</SUB>-C<SUB>4</SUB> alkyl or Benzyl.
