ABSTRACT Polymeric capsules of a rod-like shape were prepared by depositing a poly(methyl methacrylate) or polystyrene thin layer onto the surface of calcium carbonate whisker _via_ emulsion

polymerization. The obtained core/shell capsules were also converted to hollow capsules by dissolving the core material in a hydrochloric acid solution. The average thickness of the outer

shell (polymer layer) ranged from 29 to 72 nm. The glass transition temperatures _T_g’s of the outer shell were almost identical to those of the bulk both for the core/shell and hollow

capsules in contrast to the results for ultrathin polymer films, which have been reported to show significantly different _T_g from the bulk value. SIMILAR CONTENT BEING VIEWED BY OTHERS
