Title (EN) ACRYLIC ACID POLYMERS NEUTRALIZED WITH SODIUM AND CALCIUM IONS AND HAVING A NARROW MOLECULAR WEIGHT DISTRIBUTION
(FR) POLYMÈRES D'ACIDE ACRYLIQUE NEUTRALISÉS PAR DES IONS SODIUM ET CALCIUM ET PRÉSENTANT UNE ÉTROITE DISTRIBUTION DES MASSES MOLÉCULAIRES
Abstract:
(EN) An acrylic acid polymer having a weight average molecular weight Mw in the range from 3500 to 2000g/mol and a polydispersity index Mw /Mn ≤2.5, wherein 30% to 60% of the acid groups of the acrylic acid polymers have been neutralized with calcium ions, 30% to 70% of the acrylic acid polymers have been neutralized with sodium ions and 0% to 10% of the acid groups of the acrylic acid polymershave not been neutralized.
(FR) L'invention concerne un polymère d'acide acrylique présentant une masse moléculaire moyenne en masse Mw comprise dans la plage de 3500 à 2000 g/mol et un indice de polydispersité Mw /Mn ≤2,5, 30 % à 60 % des groupes acides des polymères d'acide acrylique ayant été neutralisés par des ions calcium, 30 à 70 % des polymères d'acide acrylique ayant été neutralisés par des ions sodium, et 0 % à 10 % des groupes acides des polymères d'acide acrylique n'ayant pas été neutralisés.
