METHODS OF MAKING CELLULOSE ESTER MICROBEADS WITH A SOLVENT CONTAINING WATER

Methods of making cellulose ester (CE) microbeads are provided. The CE microbeads are produced by forming initial CE microparticles suspended in a liquid phase, and converting the microparticles to hardened CE microbeads. The produced microbeads are biodegradable, and have enhanced solidity, spheric...

Zusammenfassung:	Methods of making cellulose ester (CE) microbeads are provided. The CE microbeads are produced by forming initial CE microparticles suspended in a liquid phase, and converting the microparticles to hardened CE microbeads. The produced microbeads are biodegradable, and have enhanced solidity, sphericity, and smoothness. L'invention concerne des procédés de fabrication de microbilles d'ester de cellulose (CE). Les microbilles de CE sont produites en formant des microparticules de CE initiales en suspension dans une phase liquide, et en convertissant les microparticules en microbilles de CE durcies. Les microbilles produites sont biodégradables et présentent une solidité, une sphéricité et un lissé améliorés.
