PURPOSE: To obtain the captioned polymer having a limited molecular weight distribution at a low cost by anionically polymerizing (metha)acrylic acid derivatives, (metha)acrylonitriles or the like using ammonium salts of resonance stabilized nitrogen anions as polymerization catalists.REETZ MANFRED T...
Anionic polyacrylamide is the generic name for a group of very high molecular weight macromolecules produced by the free-radical polymerization of acrylamide and an anionically charged co-monomer, mainly the sodium salt of acrylic acid, sodium acrylate. The combination of molecular weight and ionic ...
#2008 The Society of Polymer Science, Japan Anionic Polymerization of (Meth)acrylates with Trialkylsilyl-protected Lithium N-Benzylamide By Takehiro KITAURA1 and Tatsuki KITAYAMA1;Ã The polymerization of methacrylates with lithium N-benzyltrimethylsilylamide (BnTMSNLi) in the presence of aluminum ...
ANIONIC POLYMERIZATION PROCESS AND POLYMER PRODUCTION METHODA process for anionically polymerizing a (meth)acrylic acid in the presence of a tertiary organoaluminum compound (A), an organolithium compound (B) and at least one kind of a Lewis base (C) in a polymerization system. The ...
The anionic polymerization of this novel bulky silyl methacrylate has not been studied previously. In contrast to the bulky silyl monomer, trimethylsilyl methacrylate, a protected methacrylic acid with a small silyl group, can be polymerized under anionic conditions32–36 to give stereoregular polymers ...
A new photoinitiating system for anionic polymerization of acrylates based on the efficient photodecarboxylation of Ketoprofen (1) and the related derivatives3and4that generate the corresponding carbanion intermediates is presented. Carbanion intermediates are confirmed by deuterium incorporation in the trappe...
Radical copolymerization of α-cyanoacrylic ester in the presence of inhibitor for anionic polymerization About 10 mol % of acetic acid based on the cyanoacrylate was used as the inhibitor for anionic polymerization. Some electron-donating monomers, such as ... T Otsu,B Yamada - 《Kobunshi Ronb...

This invention deals with an approach to control anionic polymerization. The anionic polymerization is conducted by adding a kind of initiator ligand compound, directly or in the fo
In this example, the polymeric hydrogel for the gel/electrode complexes is prepared from an aqueous solution of monomer, crosslinking agent, and initiator by radical polymerization. The monomer for the polymer having acidic functional groups is sodium acrylate. The crosslinking agent is N,N′-methy...
