Polyalkylene glycol chain-containing thiol polymer, thiol-modified monomer, mixture thereof, and admixture for cement |
摘要 |
To provide a polyalkylene glycol chain-containing thiol polymer which is excellent in various performances, particularly significantly excellent in cement dispersibility, and useful in various applications such as an admixture for cement; a thiol-modified monomer or a mixture thereof, which can produce such a polymer; production methods of the polymer and the monomer; and a dispersant and an admixture for cement, each including the polymer. The polyalkylene glycol chain-containing thiol polymer of the present invention is a polyalkylene glycol chain-containing thiol polymer, wherein the polymer comprises a polyalkylene glycol chain and a polymer segment bonded to at least one end of the polyalkylene glycol chain with a sulfur atom-containing group therebetween, the polymer segment includes a constitutional unit derived from an unsaturated monomer component, and the unsaturated monomer component includes an unsaturated carboxylic acid monomer and an unsaturated polyalkylene glycol monomer. |
