        摘要：Swelling behavior depending on the charge density of sulfonic acid gels and acrylic acid gels in water and buffers was reviewed on the author’s results.The counterion condensation in the sulfonate gels and their volume phase transition were summarized here,showing the hystersis during the phase transition in mixed organic solvents.The driving force for the transition and concept of polyelectrolyte and ionomer were interpreted with the multiplet formation when decreasing the media polarity.

        摘要：Surface photografting polymerization (SPGP) may be intiated by the photoredution reation of an aromatic ketone with a surface H-donors,the chain transfer of a free radical to the surface of organic materials,as well as the fragmentation of a special photo-sensitive group on the surface of materials.SPGP may be conducted by a vapor phase process,a liquid phase process or a bulk phase process.The previous applications of SPGP are surface modification of organic materials,especially polyolefins.The main properties modified by SPGP are adhesiveness,printability, paintability,dyeability,anti-fogging properties,gloss,anti-static properties,lubrication, anti-staining properties,bio-compatibility,heat sealability,and so on.In recent years,extensive researches have been reported for the functionalization of a polymer surface,e.g.,the preparation of separation membrane,polymer-supported catalysts,reagents,ligands for absorption of metal ions,as well as polymer forming method.
