Descrição

Aplicação

• Chemical modification of polypropylene by maleic anhydride: This study explored the application of maleic anhydride (MAH) for modifying the properties of polypropylene through melt grafting. The findings reveal how variations in the concentration of MAH influence the polymer′s properties (Ebadi-Dehaghani et al., 2014).
• Renewable production of phthalic anhydride: A study on the synthesis of phthalic anhydride from biomass-derived furan and maleic anhydride, highlighting an eco-friendly pathway for producing a widely used industrial chemical (Mahmoud et al., 2014).
• Enhancement of biopolymer properties: Research on using maleic anhydride as a compatibilizer in natural fiber-reinforced poly(lactic acid) composites, which demonstrates the improvements in mechanical and thermal properties of the composites (Yu et al., 2014).
• Application in electrical property enhancement: This article reports on the application of maleic anhydride grafted polypropylene which significantly enhances the material′s electrical properties, potentially applicable in various advanced electronics and engineering fields (Zhou et al., 2016).
