Cement dispersants comprising graft copolymers |
摘要 |
Allyletherester monomers are prepared by an esterification reaction of alpha-allyl-omega-hydroxy-polyoxyalkylene refined so as to have peroxide value less than 5.0 meq/kg and aliphatic monocaboxylic acid under a specified condition in the absence of solvent and in the presence of an antioxidant. Allyletherester monomers thus prepared are used as an intermediate produce for the production of graft copolymers and/or their salts to be used as cement dispersant.
