The present invention provides a water absorbing agent that is excellent in a balance between a centrifugal retention capacity (CRC) and a saline flow conductivity (SFC), and a method for producing the water absorbing agent.
The method for producing the water absorbing agent, the method comprising mixing (i) a water absorbing resin (A) and (ii) a polymer (B) being a polyamine polymer having a hydroxyl group on a main chain provides a water absorbing agent containing (i) the water absorbing resin (A) and (ii) the polymer (B) being a polyamine polymer having a hydroxyl group on a main chain.

Cyclometalated palladium pre-catalyst for N-alkylation of amines using alcohols and regioselective alkylation of sulfanilamide using aryl alcohols
Simple pyrazole based palladacycle-phosphine with a high turnover has been developed and applied for the N-alkylation of amines and sulfanilamide using alcohols as substrates by hydrogen borrowing strategy. N-alkylation of primary and secondary amines resulted in high isolated yields at 100–130 °C, under solvent free conditions. More challenging secondary aliphatic as well as aromatic alcohols were
