Abstract
The manufacture of the original fluorine-containing copolymer which made the characteristics of the emulsification stability at the time of the polymerization being acquired without using the harmful emulsifier in consideration of environment or the ecosystem when obtaining the transparent novel fluorine-containing copolymer is provided. The number average molecular weight (g/mol) characteristic of consisting of the repeating unit and the polymer repeating unit of alpha- trifluoro methacrylic acid which are shown by chemical formula (1)
