        摘要：Ionic liquids (ILs) are non-volatile, non-flammable and easy-to-recycle organic salts and therefore are viewed as potential replacements of volatile organic compounds (VOCs) and used as green solvents and efficient reaction media to reduce/eliminate environmental problems in chemistry and process industries. In recent years, ILs have been successful used in polymerization reactions not only to diminish the problems resulted from VOCs but also to recycle catalysts and purify polymeric products, to more efficiently control polymerization process and the structure and properties of resultant polymers, and even to directly catalyze polymerizations. This article reviews recent advances in polymerization conducted in ionic liquid media.

        摘要：Since the 1960s,many experiments of flow-induced crystallization in polymer melts have been conducted and related models have been proposed.However,based on the strain-induced crystallization theory,the classical models have some limitations and their expectation deviates from the experimental results.In recent years, some new model approaches have been adopted to explain the flow-induced crystallization,such as the molecular model and the phenomenological model.This paper will review the essential theory and the applications of the models,compare their advantages and disadvantages,and anticipate the trend in the field of flow-induced crystallization.

        摘要：In this paper,icariin/chitosan/gelatin microspheres were achieved by emulsification and cross-linking methods.Physical and chemical characteristics of the microspheres were detected.A continual flowing system was used to determine releasing characteristics of microspheres and influencing factors.The study result indicated that the physical and chemical characteristics of microspheres were influenced by process conditions such as:rate of mixing round,quantity of emulsification and cross-linking agents,the in vitro release rate was negatively correlated with granule diameter and crossing-linking extent,positively correlated with drug contents.We can concluded that it was feasiable for chitosan and gelatin to act as carriers of slow release of microspheres,and the release rate of drug from microspheres was adjustable.

        摘要：In this paper the recent research progress on the removal of endocrine disruptors are reviewed, especially the removal of endocrine disruptors by functional polymer particles prepared using a phase transition technique from polysulfone and polyethersulfone are reviewed.The endocrine disruptors having high octanol-water distribution coefficients could bind to the polysulfone particles by hydrophobic interaction.DNA-modified particles could more effectively remove environmental hormone with a planar structure.Molecular imprinting particles have specific sites,which allow the specific recognition to endocrine disruptors and high binding amounts to specific endocrine disruptors.

        摘要：Most polymeric materials,including plastics、rubbers、fibers、coatings and so on,underwent photoaging when used outdoors and their services lifes were thus cut down.In order to protect effectively the polymeric materials from photo-deterioration,the mechanisms of photo-aging and photostabilization of polymers had been studied widespreadly and several types of light stabilizers developed successively.But since the photo-aging of polymers had been being made more and more complicated by the continuously extended ranges of use and deteriorated environment and their photo-protection becoming more and more difficult,the study of the mechanisms of photo-aging and photostabilization of polymers and development of light stabilizers were very active all the way at home and abroad.In the first part of this paper,the mechanisms of photo-aging of polymers were expounded.
