An emulsion composition of a modified polypropylene. It can have exceedingly improved emulsion stability because the modified polypropylene used has extremely high solubility in solvents and is easily emulsifiable. The modified-polypropylene emulsion composition comprises water and a modified polypropylene dispersed and emulsified therein, and is characterized in that the modified polypropylene has a racemic diad content [r] of 0.12 to 0.88 and has hydrophilic functional groups in a number of 0.5 or larger on the average per molecular chain of the polypropylene.
