摘要： By incorporating a polyoxyalkylene-modified organo(poly)siloxane compound having a specific structure as an emulsifier or emulsification aid, an organopolysiloxane having a high degree of polymerization can be easily emulsified. The obtained organpolysiloxane emulsion composition has excellent resistance to polar solvents including DMF and is dispersible in water. When incorporated into a resin composition of either the solvent-based type including an organic solvent or the water-based type, the emulsion composition can hence impart slipperiness, wear resistance, and glossiness without causing cissing or blushing.
