Rheologically Stable aqueous suspensions of Mineral material comprising Organic Polymers with low content of volatile organic compounds (VOCs)

摘要

This refers to a rheologically Stable aqueous suspensions of Mineral material comprising (a) at least one mineral material, and b) at least one polymer of Acrylic acid and / or methacrylicWhere at least one polymer of Acrylic acid and / or methacrylic is obtained by polymerization of Acrylic acid Monomer (S) and / or methacrylic in water using a compound of the formula (1) wherein X represents H or Li, na, K, and R represents an alkyl Chain which comprises 1 to 5 u00e1t Omos of carbon, and the compound of formula (1) is used in an amount of 0.1 to 2.5% by weightIt is based on the weight of the Monomer (S); (S) has a Molecular Weight in weight PM 800 to 8000 g / mol, a polydispersity Index of IP in the range of 2 to 3, and where the aqueous suspensions of Mineral material has a Content of volatile organic compounds (VOCs) with 20 mg / kg, As its process of Preparation and Uses of same.
