Methacrylate Polyglycol(400) Monoester was synthesized by strictly controlling acid/alcohol ratio,catalyst,inhibitor,temperature and 50% esterify degree. Silicagel was used to replace traditional poisonous water-carrying agent,in order to avoid separating organic solution in later and poisonous substance polluting environment. The structure of macromonomer was characterized by FT-IR and the value of unsaturated monomers was measured. The result indicate variation of double bond is 3%,which confirmed that ex...
