Latest Patents

Tetsuaki Sugita holds a patent for a "Method of producing polyetherester monomer and cement dispersants." This patent describes a process for producing high-quality polyetherester monomers through an esterification reaction of polyalkyleneglycol. The method involves using a refined closed-end of a specified kind, ensuring that residual free acid is less than 0.03 weight percent, as converted to acetic acid. The process is conducted under heated and reduced-pressure conditions, in the absence of solvents, while distilling away generated water. Additionally, cement dispersants are produced using water-soluble vinyl copolymers obtained from a radical copolymerization reaction between the polyetherester monomers and vinyl monomers.
