摘要： The present invention relates to a continuous process for preparing a comb polymer, without organic solvent, by esterification and/or amidification of an acidic homopolymer or copolymer, which consists in performing the esterification and/or amidification of said homopolymer/copolymer by reaction at elevated temperature in the mixing and transportation zone of a tubular reactor, optionally equipped with a water removal system, in the presence of at least one poly(alkylene glycol) in solid or molten form and of an antioxidant, said esterification and/or amidification taking place at a temperature greater than or equal to 170° C.

摘要： Novel copolymers obtained by polymerisation a mixture of monomers comprising: at least one anionic monomer (a) comprising a polymerisable unsaturated function and a carboxylic group; and at least one monomer (b) of formula (I): H2C═C(—R1)-(CH2)p—O—[(EO)n-(PO)m]-H  (I) where [(EO)n-(PO)m] represents a polyalkoxylated chain consisting of ethoxylated units EO and propoxylated units PO, distributed into blocks, alternating or statistical, the molar proportion of the ethoxylated units in the polyalkoxylated chain (n)/(m+n) being greater than or equal to 70% and strictly less than 90%. In addition, hydraulic composition, for example concrete compositions, comprising such copolymers, and the use of said copolymers as water-reducing agents in hydraulic compositions and for increasing the early mechanical strength of a hydraulic composition.

摘要： The present invention pertains to the use, in the manufacture of an aqueous formulation with a hydraulic binder base, of a combination of at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one ASE acrylic polymer. This results in improving the workability of said formulation, without causing a segregation phenomenon.
