Abstract:
The present invention relates to a poly(alkylene carbonate) capsule in which a heterogeneous resin is applied on a surface of poly(alkylene carbonate), and a method of manufacturing the same, and provides a poly(alkylene carbonate) capsule preventing blocking where particles agglomerate each other when a resin having surface stickiness at a glass transition temperature or higher is processed in a pellet or chip state and circulated, and a method of manufacturing the same.
