摘要： Provided is a method for producing water-absorbent resin particles, which is capable of improving the gel strength for the purpose of achieving a good balance between the absorption under load and the rate of liquid permeation through gel. The present invention is a method for producing water-absorbent resin particles, which is characterized by comprising a step wherein a monomer composition containing a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2) that turns into a water-soluble vinyl monomer (a1) by means of hydrolysis and a crosslinking agent (b) is polymerized in the presence of at least one organic main group element compound selected from the group consisting of organic iodine compounds, organic tellurium compounds, organic antimony compounds, and organic bismuth compounds.

摘要： Metal ion sequestering particles were formed in a one-pot single step synthesis by azeotropically removing water while heating a reaction mixture containing a branched poly(ethylenimine), poly(acrylic acid), di-(2-picolylamine), a catalytic amount of N,N-duimethylformamide, toluene, and either glycine or a carboxy-terminated poly(N-isopropylacrylamide). No other catalyst was present. The branched and crosslinked particles formed using the poly(N-isopropylacrylamide) sequestered metal ion from water at ambient temperature and released the bound metal ion upon heating.

摘要： To provide a method for producing a polymer that is capable of providing an alkenyl ether polymer having a molecular weight, a molecular weight distribution, and a composition that are controlled, with a vinyl ether having a hydroxyl group, and a block copolymer thereof. To provide a polymer obtained by the method as a macro chain transfer agent capable of performing reversible addition fragmentation chain transfer polymerization. Livingness can be imparted to radical polymerization of a hydroxyl group-containing vinyl ether by performing the radical polymerization in the presence of a particular RAFT agent and a radical polymerization initiator, and a block copolymer with another radically polymerizable vinyl monomer can be obtained by using the resulting living polymer as a macro chain transfer agent capable of performing reversible addition fragmentation chain transfer polymerization.

摘要： Disclosed herein are embodiments of methods for making and using functionalized forms of polydicyclopentadiene polymers. The disclosed polymers and methods enable a greater range of uses than the unmodified polydicyclopentadiene, which is currently used industrially. In addition, the presence of the functional groups contemplated by the disclosed compounds and formulae allow for the control of the polymer surface energy, and also enables the use of reversible chemical crosslinks, which permits recycling of the material.
