20100137477 | WORKABILITY OF AN AQUEOUS FORMULATION WITH A HYDRAULIC BINDER BASE USING A COMBINATION OF COMB-BRANCHED POLYMERS - The invention pertains to improving the workability of an aqueous formulation with a hydraulic binder base using a combination between 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 comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophobic group. | 06-03-2010 |
20100267564 | METHOD FOR ENCAPSULATING OILS IN AN AQUEOUS MEDIUM WITH HASE POLYMER EMULSIONS, PRODUCTS OBTAINED, AND USES THEREOF - The invention consists of a method for manufacturing an aqueous formulation containing at least one oil, and comprising the steps of mixing at least one associative polymer, one oil, and water, encapsulating the oil by increasing the pH to a value greater than 8, potentially precipitating the mixture by reducing the pH to a value less than 6, and potentially isolating the resulting particles by removing the water. The aqueous formulations, as with the aqueous dispersions, and the resulting solid particles constitute other objects of the invention. | 10-21-2010 |
20100273923 | METHOD OF MANUFACTURING COMB POLYMERS BY ADDING AN ANTIOXIDANT, POLYMERS OBTAINED, AND APPLICATIONS THEREOF - The invention resides in the implementation of an antioxidant during the functionalization reaction of a (meth)acrylic polymer in a dry state by polyoxyalkylated lateral groups, so as to improve the grafting rate of the final polymer. The obtained polymers constitute another object of the invention, as do the aqueous formulations that they contain. | 10-28-2010 |
20110207855 | AQUEOUS SOLUTION OF (METH)ACRYLIC FLUID COMB-BRANCHED POLYMERS WITH A SOLID CONTENT GREATER THAN 60%, MANUFACTURING METHOD AND USE AS A PLASTICIZING AGENT - The present invention pertains to an aqueous solution of comb-branched polymers, having a (meth)acrylic skeleton functionalized by side-chains with hydrophilic alcoxy- or hydroxy-polyalkylene glycol functions, said solution remaining stable and workable at dry solids content levels greater than 60% of its weight. The invention also pertains to a method for manufacturing such solutions, as well as their use as a plasticizing agent, and hydraulic binder-based compositions containing them. | 08-25-2011 |
20110207856 | USE AS AN AGENT IMPROVING THE WORKABILITY OF AN AQUEOUS FORMULATION WITH A HYDRAULIC BINDER BASE, OF A (METH)ACRYLIC COMB-BRANCHED COPOLYMER AND AN ASSOCIATIVE ACRYLIC THICKENER - 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. | 08-25-2011 |
20150051319 | USE AS AN AGENT IMPROVING THE WORKABILITY OF AN AQUEOUS FORMULATION WITH A HYDRAULIC BINDER BASE, OF A (METH)ACRYLIC COMB-BRANCHED COPOLYMER AND AN ASSOCIATIVE ACRYLIC THICKENER - 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. | 02-19-2015 |
20150240047 | METHOD FOR PRODUCING A MASTER MIXTURE BASED ON CARBONACEOUS NANOFILLERS AND SUPERPLASTICISER, AND THE USE THEREOF IN HARDENABLE INORGANIC SYSTEMS - Hardenable inorganic systems such as cements, plasters, ceramics or liquid silicates, usable for example in the building trade, construction industry or oil drilling industry. The insertion of carbonaceous nanofillers, such as carbon nanotubes, for reinforcing mechanical properties and improving such systems.
