Abstract
The present invention relates to a new solvent-free preparation method of a (meth)acrylic acid polymer in solution, where said polymer has a molecular weight less than 8,000 g/mol and a polydispersity IP index between 2 and 3 by radical polymerization, the polymers obtained by this means, and their applications in industry.
