摘要： There is provided a novel ionic composite material that can be molded into various shapes using lignin sulfonic acid as one of raw materials thereof, and having flexibility and elasticity, to significantly improve the strength and toughness and impart complete biodegradability thereto. It was found that a combination of ε-polylysine (ε-PL) which is a cationic polymer that is produced by microorganisms and lignin sulfonic acid exhibits excellent strength and toughness. In addition, ε-PL used in this technology is a biodegradable polymer that is completely degraded by microorganisms and the like in the environment. Since lignin sulfonic acid is also a biodegradable polymer, it is thought that a complex in which ε-PL and lignin sulfonic acid are mixed in this technology will exhibit complete biodegradability, and more applications thereof can be expected when utilizing the strength, durability, and biodegradability thereof in addition to the improved strength and toughness.

摘要： The present invention relates to a drug delivery system comprising a core and a shell in which the core comprises a hydrolytically degradable polymer X which polymer backbone comprises pendant ester and acid functionalities and in which the shell comprises a hydrolytic degradable polymer Y. The hydrolytic degradable polymers X and Y are different polymers. Polymer X further comprises amino-acids in the polymer backbone and degrades via zero order degradation kinetics for a period of at least 3 months. Polymer Y degrades via auto-acceleration degradation kinetics.

摘要： The present disclosure provides a leaching process and resulting composition which prevents or substantially reduces agglomeration of polyamide 6/66 copolymers. The leaching process includes applying hot water in the presence of an agglomeration inhibitor to the polyamide 6/66 copolymers in order to separate unreacted caprolactam and small molecular weight oligomers from the copolymers while preventing or substantially reducing agglomeration of the copolymers.
