A binary copolymer water treatment agent was synthesized by using maleic anhydride and sodium allyl sulfonate as raw materials ammonium persulfate initiator. The scale inhibition dispersion properties of the were studied through static experiments. results show that has excellent performance. Moreover, polymer is an environment-friendly with good application prospects.
Polyamide polymers have moderate mechanical properties, excellent wear resistant properties, and solvents. However, polyamides have some disadvantages such as notch sensitivity and high water absorption. Generally, polyamides are ductile in the un notched state but they show brittle behavior in the state of notched impact. Some disadvantages of polyamides can be improved by some fillers and add...
While mechanosynthesis of the target compound, 1-[2-(1H-indol-3-yl)-ethyl]-pyrrole-2,5dione, C14 H12 N2 O2, did not yield the desired product, it instead resulted in an open intermediate. On the other hand, synthesis starting from the activated maleic anhydride yielded the final maleimide compound. The outcome of the mechanosynthesis has been evaluated by powder X-ray diffraction, and structure...
Petrochemical based polymers, paints and coatings are cornerstones of modern industry but our future sustainable society demands greener processes renewable feedstock materials. A challenge is to access platform monomers from biomass resources while integrating the principles green chemistry in their chemical synthesis. We present a synthesis route starting biomass-derived furfural towards comm...
nanocomposites based on polyamide 6 (pa6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (eb-g-mah) blends have been prepared via melt mixing. the effect of blend ratio and organoclay concentration onthe crystallization and melting behavior of specimens were studied. three types of commercial organo-modifiedclay (cloisite 30b, cloisite 15a and cloisite 20a) were employed to assess the im...
The behavior of stone groundwood / polypropylene injection-molded composites was evaluated with and without coupling agent. Stone groundwood (SGW) is a fibrous material commonly prepared in a high yield process and mainly used for papermaking applications. In this work, the use of SGW fibers was explored as a reinforcing element of polypropylene (PP) composites. The surface charge density of th...
Wood as a natural renewable material is vulnerable to degradation by microorganisms and susceptible to change in dimension by water. In order to effectively improve the durability of wood, an active reagent, maleic anhydride (Man) was selected for wood modification. Man was first dissolved into a solvent, and then penetrated into wood porous structure under a vacuum/pressure condition. After a ...
