Title:
複合フィルムの積層のためのオキサゾリン含有水性ポリマー分散体
Document Type and Number:
Japanese Patent JP6789967
Kind Code:
B6
Abstract:
Described are aqueous polymer dispersions for composite film lamination and a multistage process for preparing them from ethylenically unsaturated, radically polymerizable monomers. In a first stage, a first polymer is prepared by radical emulsion polymerization. In a further stage, an aqueous polymer dispersion is prepared in the presence of the first polymer. The monomers of the first stage comprise monomers with acid groups. The monomers of the further stage comprise monomers having oxazoline groups. The polymerization of the first stage takes place at a low pH of less than 5. The acid groups of the first polymer are neutralized before the polymerization of the further stage. The aqueous polymer dispersions can be used as adhesives for producing composite films.
