  grafted technical conditions
     A series of environmental responsive gating membranes were prepared by grafting methacrylic acid(MAA) onto two organic substrates,including porous polyvinylidene fluoride(PVDF) membranes and nylon(N6) membranes,and onto inorganic substrate porous anodic aluminum(PAA) membranes,with plasma-induced graft polymerization. Effects of porous membrane substrates and grafted technical conditions on microstructures of grafted gating membranes have been systematically studied.

The article deals with reactive extrusion for grafting of Maleic Anhydride (MAH) on Polypropylene (PP) in a single-screw extruder The effects of PP types, added amount of DCP, the ratio of MAH/DCP,and extrusion conditions on grafting ratio and melt viscosity of products were investigated It was found that DCP concentration and the value of MAH/DCP would substantially influence the grafting ratio, which tended to show peak-like changes with increase of both DCP concentration and MAH/DCP; the extent of thermal...

The article deals with reactive extrusion for grafting of Maleic Anhydride (MAH) on Polypropylene (PP) in a single-screw extruder The effects of PP types, added amount of DCP, the ratio of MAH/DCP,and extrusion conditions on grafting ratio and melt viscosity of products were investigated It was found that DCP concentration and the value of MAH/DCP would substantially influence the grafting ratio, which tended to show peak-like changes with increase of both DCP concentration and MAH/DCP; the extent of thermal and oxidative degradation on PP macromolecules during the melt grafting reaction was related with PP types, DCP concentration and extrusion conditions. By selection of suitable extrusion conditions and use of some additives, the degradation of PP could be limited to some extent

The 300%~700% of total grafting percentage could be obtained as the suitable grafting reaction conditions were selected. Changing the feed composition or feed methods of monomers in batches could control the ratio and series structure of styrene and 4\|vinylpyridine on grafted fiber. After sulphonated with sulphonyl chloride, an expected amphoteric fiber could...
