PROBLEM TO BE SOLVED: To provide a polyalkylene glycol macromonomer having high cost-efficiency and storage stability and giving a copolymer with other unsaturated comonomer having a hydrolysis-resistant chemical bond of the polyether side-chain of the copolymer. SOLUTION: The compound is expressed by formula 1 or formula 2. The compound is used as a polymerizable emulsifier. In the formulas, A is a 2-4C alkylene; n is an integer of 4-900; m is an integer of 1-50; R is hydrogen, an m-valent acid group or a 1-200C m-valent organic group; and the organic group may contain hetero-atoms such as oxygen, nitrogen, sulfur and phosphorus in addition to carbon and hydrogen.
