Polymerization process of (meth) acrylic acid in solution, polymer solutions obtained and their uses |
| abstract |
Process for the preparation without solvent of a polymer of (meth) acrylic acid in solution, said polymer having a molecular mass of less than 8000 g / mol and an IP polydispersibility index of between 2 and 3, comprising the following steps: a) introduces water into a synthesis reactor, and optionally a catalyst based on water-soluble metal salts, b) the reactor is heated to a temperature of at least 60 ° C, c) the following compounds are continuously and simultaneously introduced into the reactor : b1) the (meth) acrylic monomer (s) to be polymerized b2) at least one compound of formula (I): ** Formula ** according to which: - X represents Na, K or H, and -R represents an alkyl chain comprising from 1 to 5 carbon atoms b3) a polymerization initiator system, the mass percentage (weight / weight) between said compound of formula (I) and said monomer (s) being comprised ) (meth) acrylic (s) between 0.1 and 2.5%. |
