Title:
AQUEOUS EMULSION AND ADHESIVE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/235924
Kind Code:
A1
Abstract:
The present invention provides an aqueous emulsion which has excellent heat resistance, water resistance (especially, hot water resistance and boiling resistance) and viscosity stability. The present invention relates to an aqueous emulsion which contains, as a dispersoid, a polymer (A) containing an ethylenically unsaturated monomer unit, while containing, as a dispersant, a vinyl alcohol polymer (B), and which is configured such that the polymer (A) containing an ethylenically unsaturated monomer unit contains a structural unit derived from a radically polymerizable, ethylenically unsaturated monomer (p) that has a functional group represented by general formula (P) and a structural unit derived from a radically polymerizable, ethylenically unsaturated monomer (q) that has a functional group represented by general formula (Q). (In the formulae, X and Y may be the same or different and each represents an oxygen atom or a sulfur atom; Z represents an oxygen atom or a nitrogen atom; * represents a bonding hand; and m represents 1 or 2.)
