    摘要： Spheroidal shaped, hollow microcapsules of thermoplastic polymeric resins have been prepared which have an average diameter of from 0.1 Mu to 1.0 Mu . Each of the microcapsules are filled with air and have an average wall thickness of from about 3 percent to 30 percent of the diameter of the microcapsules. These microcapsules are obtained from an emulsion comprising water and microcapsules of the polymeric resin containing a nonsolvent for the resin. The microcapsules are suspended in the water and the non-solvent is present inside the microcapsules. Either one of these products, i.e. the microcapsules themselves or the water emulsion containing the microcapsules described above, may be used as an opacifier in paint or other systems.
