The present invention relates to an aqueous dispersion of neutralized multistage polymer particles comprising an alkali metal base or a high boiling point amine salt of a carboxylic acid functionalized first stage, and a low T.sub.g second stage (shell). The dispersion is useful as an open time additive.

A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.

There is provided a water-absorbent resin that exhibits a high liquid-retention capacity under a load and a small amount of re-wet even when it is used in an absorbent material having a low proportion of hydrophilic fibers.

A water-absorbent resin comprising a polymer of a water-soluble ethylenically unsaturated monomer, wherein when a cross-sectional image of the water-absorbent resin is observed using X-ray computed tomography, the water-absorbent resin has a ratio of the area of cavity portions (cavity area ratio) in the cross-sectional image of 10% or less, as calculated according to Equation (I):

cavity area ratio [%]={total cross-sectional area of cavity portions (B) in the water-absorbent resin/(total cross-sectional area of resin portions (A) in the water-absorbent resin+total cross-sectional area of cavity portions (B) in the water-absorbent resin)}100(I).

The present disclosure relates to an electrode binder composition for a rechargeable battery and an electrode mixture including the same. The electrode binder composition comprising an emulsified polymer particle having a core-shell structure can maintain a structural stability of the electrode even in repeated charge and discharge cycles, while having excellent properties in terms of a binding force, a mechanical property or the like, thereby improving the overall performance of the rechargeable battery.

The present invention teaches a composition and process for irreversibly agglomerated charge stable core shell microcapsules, each microcapsule containing a benefit agent core material, which may be the same or different, the polymeric all or walls comprising one or more (meth)acrylate polymers, or optionally combinations with other polymers, along with a polyvalent cation. The capsules of the invention adhere better to surfaces, are more stable and are useful for delivery of benefit agents.
