Document Type and Number:
Japanese Patent JP2004532305
Kind Code:
A
Abstract:
Aqueous dispersions entirely or substantially free from volatile organic compounds, comprising (A) at least one block copolymer preparable by two-stage or multistage free-radical copolymerization in an aqueous medium of a) at least one olefinically unsaturated monomer selected from the group consisting of hydrophilic and hydrophobic olefinically unsaturated monomers, and b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula I R1R2C-CR3R4 (I) in which the radicals R1, R2, R3 and R4 each independently of one another are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R1, R2, R3 and R4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; and (B) hydrophilic nanoparticles; processes for preparing them, and their use as or to prepare coating materials, adhesives, and sealing compounds.
