Abstract: To provide hollow particles excellent in dielectric property and solvent resistance and able to decrease the permittivity and dielectric dissipation factor of a resin molded body, and a method for producing the hollow particles. Hollow particles which comprise a shell containing a resin and a hollow portion surrounded by the shell and which have a void ratio of 50% or more, wherein the shell contains, as the resin, a polymer in which 70% by mass or more of a crosslinkable hydrocarbon monomer unit is contained, and wherein, in a hollow particle immersion test in which a mixture obtained by adding 0.1 mg of the hollow particles to 4 mL of toluene and shaking them for 10 minutes at a shaking rate of 100 rpm, is left to stand for 48 hours in an environment at 25° C., less than 5% by mass of the hollow particles submerge in the toluene.

Abstract: This disclosure relates to a biodegradable core-shell microcapsule that includes (a) a shell containing the reaction product of an isocyanate-functionalized prepolymer with a crosslinker and optionally a polyelectrolyte under an aqueous condition, and (b) a core containing an active material, wherein the isocyanate-functionalized prepolymer is the reaction product of a polyisocyanate with a biopolymer and/or an amphiphilic compound under an anhydrous condition, and the microcapsule shell is substantially free of or free of a self-condensed polyisocyanate. This disclosure also relates to a process of preparing such biodegradable core-shell microcapsule. This disclosure also relates to a consumer product containing such biodegradable core-shell microcapsule. This disclosure also relates to a process of making the isocyanate-functionalized prepolymer.
