Combination cellulose materials and methods of making and using these materials. The combination material includes a first cellulosic material and a second cellulosic material.

The present invention pertains to a process for manufacturing a vinylidene fluoride polymer, to a polymer obtainable via said process and to an article comprising the same.

Disclosed herein are a biodegradable polymer microparticle for a filler, a freeze-dried body including the same, a manufacturing method thereof, and filler injection including the freeze-dried body. The freeze-dried body includes hydrophilic surface-treated biodegradable polymer microparticle and a biocompatible carrier, wherein the hydrophilic surface-treated biodegradable polymer microparticle has an average particle diameter (D.sub.50) of 20 to 50 μm and is polydioxanone which has a carboxyl group on the surface thereof. The hydrophilic surface-treated biodegradable polymer microparticle is a plasma surface-treated product or a base surface-treated product using discharge of the biodegradable polymer microparticle. The content of the biocompatible carrier is 1 to 5 parts by weight based on 100 parts by weight of the freeze-dried body.
