<P>PROBLEM TO BE SOLVED: To provide a thiol-modified monomer mixture which is excellent in various performances, particularly significantly excellent in dispersibility, and capable of providing a component which is useful in various applications such as an admixture for cement, a polyalkylene glycol chain-containing thiol polymer obtained by using the monomer mixture and a dispersant and an admixture for cement, each including the polymer, and a cement composition. <P>SOLUTION: The thiol-modified monomer mixture has a structure represented by general formula (1) and/or general formula (2) (wherein R<SP>1</SP>and R<SP>2</SP>may be same or different and represent organic residues; AO may be same or different and represent at least one kind of 2-18C alkylene glycol group; n represents average number of moles of oxyalkylene group and is an integer of 80-500 and R<SP>3</SP>is a hydrogen atom or an organic residue). <P>COPYRIGHT: (C)2009,JPO&INPIT |
