Abstract
Improvements introduced in the object of the main patent no. 370,329 on a process to avoid petrifying sedimentations in aqueous systems, characterized in that a mixture consisting of a) aminoalcohilane phosphonic acid and b) a graft polymer based on a polysaccharide and acrylic acid or methacrylic acid or mixtures of the monomers with each other or with other unsaturated compounds, in a weight ratio of a: b of approximately 1: 1 to 1:50, preferably 1: 4 to 1:20, in amounts less than the stoichiometric ones referred to hardness forming agents.
