COATING LIQUID COMPOSITION, SUBSTRATE WITH COATING FILM, SEPARATOR, SECONDARY BATTERY, AND ELECTRODE MATERIAL
Provided is a coating liquid composition that is less likely to deform even when heat is applied to a coating liquid for a paint mainly containing a polymer, an ink, an adhesive, and an anode, a cathode, or a separator of a lithium ion battery, for example. The coating liquid composition includes a filler, a solvent, a dispersant, and a thickener. When the coating liquid composition is applied to a substrate to form a coating film having a thickness of 0.5 to 20 μm, the coating film has a shrinkage rate of 20.0% or less when heating at 200° C. for 15 minutes.
METHOD FOR PRODUCING AN AQUEOUS POLYMER DISPERSION FROM A VINYL AROMATIC COMPOUND AND A CONJUGATED ALIPHATIC DIENE
The present invention relates to a process for preparing an aqueous polymer dispersion by radically initiated aqueous emulsion polymerization, which comprises polymerizing
TABLE-US-00001 (a) 40 to 75 parts by weight of at least one vinylaromatic compound, (b) 24.9 to 59.9 parts by weight of at least one conjugated aliphatic diene, (c) 0.1 to 10 parts by weight of at least one monomer containing acid groups, an (d) 0 to 20 parts by weight of at least one other monoethylenically unsaturated monomer, where the amounts of the monomers (a) to (d) add up to 100 parts by weight,
in an aqueous medium by a monomer feed process, with the proviso that monomers and emulsifier are metered continuously and following a period P1, when 15 to 30% of the total monomer metering time has elapsed and 15 to 30 wt % of the total monomer amount has been metered in, the metering rate of the emulsifier is increased for a period P2 lasting no longer than 30 minutes to 10 to 100 times the average metering rate of the emulsifier in the period P1,
and also to the aqueous polymer dispersions prepared by the process and to the use thereof as a binder, adhesive, fiber sizing agent, for producing coatings or for producing a paper coating slip.
