Synthesis and Characterization of Maleic Anhydride Grafted ...
2013年5月20日 · This paper discusses a new chemical route that can form PP-g-MAH with desirable MAH content, a single MAH incorporated unit, white color, high molecular weight, and narrow molecular weight and composition distributions.
A new method for preparing anhydride grafted polypropylene …
2023年7月24日 · Maleic anhydride grafted polypropylene (PP-g-MAH) is an effective compatibilizer in the preparation of polypropylene composites. Its grafting ratio plays an important role in the dispersion of filler or blend in polypropylene (PP) matrix resin, but the grafting ratio of PP-g-MAH prepared by reactive extrusion is low.
Functionalization of isotactic polypropylene with maleic anhydride …
2001年6月1日 · Independent of the initial concentration of the MAH monomer, the grafting degree of PP-g-MAH increases with increasing the loading level of DCP, at least in the range of 0.6–5 wt%. The higher the concentration of DCP, the higher the grafting degree of PP- g -MAH and the more the peak value shifts towards high MAH concentrations.
Effect of Polypropylene Grafted Maleic Anhydride (PP-G-MAH) on …
2022年4月26日 · At a higher dosage of PP-g-MAH (i.e., 7%–9%), the viscosity remains almost unchanged because PP-g-MAH is in excess in comparison to the asphalt content. The PP-g-MAH content has a significant effect on the pumping, mixing, and …
PP-g-MAH, Fusbond MD-353D with grafting percentage 2%, was purchased from DuPont. In a typical pretreatment process of halloysites with the silane, ethanol water solution (200 mL) (95 vol %) was...
Investigation of Interfacial Diffusion in PA/PP-g-MAH Laminates …
In the PA/PP-g-MAH laminate, an interfacial layer is formed due to diffusion between the PA and PP-g-MAH phases (c). This strengthens the interface and stabilizes the system under shear deformation (d).
Improvements of polypropylene grafted maleic anhydride with ...
2011年1月15日 · Polypropylene (PP) grafted maleic anhydride (MAH) has been widely studied over the past several decades because of the product PP- g -MAH, which can be used as a compatilizer in polymer blends, as an adhesion promoter with glass or carbon fiber, and even as a processing aid for recycling of plastics waste [1].
The Impact of PP-g-MAH on Mechanical Properties of Injection
2024年1月29日 · Mechanical and physical properties of the LFTP were investigated by introducing PP-g-MAH at concentrations of 4, 8, and 12 wt% through injection molding. The results revealed that, at a 4 wt% concentration of PP-g-MAH, the LFTP composites exhibited heightened tensile, flexural and impact strengths.
Property improvement and compatibilization mechanism of …
2022年11月15日 · In this work, maleic anhydride (MAH) and maleic anhydride grafted polypropylene (PP-g-MAH) were used as additives to modify PLA/PP blends by changing the ratio content of raw material and melt blend composition, to obtain nonwoven slices to produce nonwoven fabrics and fibers.
高接枝率PP-g-MAH的制备及其在PP/GF中的应用 - Semantic Scholar
2016年3月26日 · 对传统双螺杆反应挤出机进行工艺改进，研究了辅助接枝单体和不同半衰期引发剂的分段加入工艺对马来酸酐熔融接枝聚丙烯（pp-g-mah）的影响。
