| titleOfInvention | Procedure to polymerize met (acrylic) acid in solution, polymer solutions obtained and uses thereof |
| abstract | Solvent-free preparation process of a (meth) acrylic acid polymer in solution, the said polymer has a molecular mass of less than 8000 g / mol and a polydispersity index (PI) of between 2 and 5, characterized because it comprises the following stages: a) water is introduced into a synthesis reactor, b) the reactor is heated to a temperature of at least 60 ° C, c) the following compounds are introduced into the reactor continuously and simultaneously: c1) the (meth) acrylic monomer (s) to be polymerized, c2) a polymerization initiator system, c3) a compound of formula (I): ** (See formula) ** according to which: - X represents Na, K or H, and -R represents an alkyl chain comprising 1 to 5 carbon atoms, in an amount such that the mass percentage (weight / weight) between the compound of formula (I) and the monomer o (meth) acrylic monomers (s) is between 0.1 and 2.5%, a process according to which, during step a) and / or step c), hypophosphite sodium NaPO2H2 or a derivative thereof is introduced into the synthesis reactor in a total amount in such a way that the percentage of mass (weight / weight) between NaPO2H2 and said monomer or monomers (meth) acrylic (s) is between 2 , 9 and 5.8% by weight. |
