    Abstract: The present invention provides a process for producing thermo-expansive microspheres comprising a thermoplastic resinous shell and a blowing agent being encapsulated in the shell, the blowing agent which is a fluorine-containing C2-10 compound having ether linkage, being free of chlorine and bromine atoms and gasifying at a temperature not higher than the softening point of the thermoplastic resin. The thermo-expansive microspheres have preferably an average particle size ranging from 1 to 100 μm and a CV, or coefficient of variation, of particle size distribution being 30% or less, and a retaining ratio of blowing agent encapsulated being 90% or more.

    Abstract: A production process for heat-expanded microspheres comprising the step of providing a gaseous fluid containing heat-expandable microspheres, which comprise shell of thermoplastic resin and a blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin and have an average particle size from 1 to 100 μm, feeding the gaseous fluid through a gas-introducing tube having a dispersion nozzle on its outlet and being fixed inside a hot gas flow, and emitting a jet of the gaseous fluid through the dispersion nozzle; a step wherein the gaseous fluid is collided on a collision plate fixed under the dispersion nozzle so as to disperse the heat-expandable microspheres in the hot gas flow; and a step wherein the dispersed heat-expandable microspheres are heated in the hot gas flow at a temperature not lower than their expansion initiating temperature and thus expanded. The production process results in minimum difference in the variation coefficient of particle size distribution between the microspheres before and after heat-expansion, slight ratio of raw microspheres and slightly expanded microspheres contained in resultant heat-expanded microspheres, and suppressed formation of aggregated microspheres.

The gaseous fluid is fed through a gas-introducing tube having a dispersion nozzle on its outlet that is fixed inside a conduit having a hot gas flow flowing therethrough. A jet of the gaseous fluid is emitted through the dispersion nozzle. Further, the gaseous fluid is collided on a collision plate fixed under the dispersion nozzle so as to disperse the heat-expandable microspheres in the hot gas flow. The dispersed heat-expandable microspheres are heated in the hot gas flow at a temperature not lower than their expansion initiating temperature and thus expanded.
