<p>The objective of the present invention is to provide an ethylene-based composite resin composite particle having a small-sized, approximately spherical form, comprising functional filler homogeneously dispersed therein, and being compatible with other resin pellets or components. To attain the above objective, the present invention provides an environmentally friendly method for producing an ethylene-based resin composite particle, comprising: (a) dissolving ethylene-based polymer in organic solvent separable from aqueous phase and dispersing hydrophobic filler in environment-friendly organic solvent to form solution of ethylene-based polymer in the organic solvent; (b) emulsifying the solution obtained in step (a) in non-ionic surfactant-containing aqueous solution; (c) heating the emulsion obtained in step (b) to remove the organic solvent; and (d) recovering a precipitate the ethylene-based resin composite particle containing the hydrophobic filler therein. The present invention also provides an ethylene-based resin composite particle produced by the afore-mentioned process.</p> |
