DISPERSION AQUEUSE DE POLYMÈRE, SON UTILISATION ET PROCÉDÉ DE PRÉPARATION D'UNE DISPERSION AQUEUSE DE POLYMÈRE

摘要

The invention relates to an aqueous polymer dispersion having a viscosity of ≤150 m Pas at 40% solids content and comprising polymer particles having a particle size D50 less than 85 nm. The polymer dispersion is obtainable by free radical emulsion copolymerisation of at least monomer (a) and monomer (b), where monomer (a) is at least one optionally substituted styrene and monomer (b) is at least one C1-C4-alkyl (meth)acrylate, in a reaction mixture comprising degraded starch which has an average molecular weight Mn<1000 g/mol. The invention relates also to the use of the polymer dispersion and method for preparing it.
