Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A poly(propylene carbonate) capsule in which a dissolved heterogeneous resin satisfying the following Equations 1 and 2 is applied on a surface of poly(propylene carbonate): 70≦T≦270 [Equation 1] 5,000≦Mw≦200,000 [Equation 2], wherein T represents a melting point or a softening point in ° C., and Mw represents a weight average molecular weight in g/mol, and wherein the heterogeneous resin is one or a mixture of two or more selected from, poly(butylene adipate-co-butylene-terephthalate), poly(butylene succinate), poly(butylene succinate-co-butylene adipate), cellulose acetate, triacetate cellulose, polyvinylpyrrolidone, starch, styrenebutadienestyrene, acrylonitrilebutadienestyrene, styrenemaleic anhydride, polylactic acid, and a copolymer of lactide-glycolide. 2. The poly(alkylene carbonate) capsule of claim 1 , wherein the poly(alkylene carbonate) includes one or a multiple polymer of two or more selected from ethylene oxide, propylene oxide, glycidyl alkyl ether, glycidyl acrylate, and diglycidyl ether. 3. The poly(alkylene carbonate) capsule of claim 1 , wherein 0.5 to 10 parts by weight of the heterogeneous resin is included based on 100 parts by weight of the poly(alkylene carbonate). 4. A poly(propylene carbonate) capsule in which a dissolved heterogeneous resin is applied on a surface of poly(propylene carbonate), wherein the heterogeneous resin is one or a mixture of two or more selected from polyamide, poly(butylene adipate-co-butylene-terephthalate), poly(butylene succinate), poly(butylene succinate-co-butylene adipate), cellulose acetate, triacetate cellulose, polyvinylpyrrolidone, styrenebutadienestyrene, acrylonitrilebutadienestyrene, styrenemaleic anhydride, polylactic acid, and a copolymer of lactide-glycolide.
