Disclosed herein are hydrophobic vinylamine-containing polymers useful as papermaking performance additives for enhancing paper softness with little or no negative effect on paper dry strength properties. The hydrophobic vinylamine-containing polymers are produced by incorporating hydrophobic functional property into primary amine moiety of the vinylamine-containing polymers via reactions with reactive hydrophobes. The hydrophobically modified vinylamine-containing polymers can be further used as base polymers for polymerization with a vinyl monomer by free radical initiated polymerization. The compositions of those hydrophobic vinylamine-containing polymers have shown improved softness, reduced coefficient friction to paper products while maintained or improved dry strength properties of the paper products.

and dispersing the compound represented by the formula (I) into the water-containing rubber solidified product including the carbon black while dehydrating the rubber solidified product including the carbon black to produce a wet rubber masterbatch; and (iv) adding, to the resultant wet rubber masterbatch, the compound represented by the formula (I) and an antiaging agent further, and dry-mixing these substances with each other.

Disclosed are novel phosphono-phosphate polymer compositions with multi-valent cations in aqueous solutions. These compositions can further include mono or multivalent anions.

Disclosed is a method for recovering and processing a retired battery electrode plate. The method includes disassembling a retired battery to obtain an electrode plate, energizing two ends of the electrode plate until a binder on the electrode plate is heated and melted, and then separating out an electrode material and a current collector, and when the electrode plate is a negative electrode plate, ball milling the separated electrode material, winnowing the ball-milled material to obtain graphite, subjecting the graphite to an alkali treatment, adding the graphite, which has been subjected to the alkali treatment, and an aggregate to softened asphalt, and stirring same to obtain conductive asphalt. The two ends of the electrode are energized, such that the binder is melted into liquid to flow out of the current collector, and the electrode material is stripped off the electrode plate.
