USE OF AQUEOUS POLYMER DISPERSIONS FOR IMPROVING RESISTANCE TO CHEMICAL INFLUENCES |
摘要 |
Coating compositions containing an aqueous polymer dispersion having improved resistance toward chemicals. The aqueous polymer dispersion is prepared by polymerizing a first composition containing at least one ethylenically unsaturated group (monomers) by radical aqueous emulsion polymerization and then, in the presence of a product mixture from the previous polymerization, polymerizing a second composition containing at least one ethylenically unsaturated group (monomers) by radical aqueous emulsion polymerization. The coating compositions are such that the difference between a glass transition temperature of a polymer prepared from the first polymerization and a glass transition temperature of a polymer prepared from the second polymerization is at least 50° C.
