Abstract:
This paper reviews current scientific publications on the influence of maleic anhydride on the structure of polypropylene, its blends, and other modified materials, as well as the development of alternative synthesis methods and applications. It is shown that in recent years, alongside traditional methods for synthesizing maleated polypropylene, alternative approaches have been actively developing. These primarily involve modifying the reaction medium with various chemical compounds or exploring new synthesis methods and instrumentation. Among the many published papers, studies devoted to the surface grafting of maleic anhydride using microwave technologies and nanoreactors stand out. A promising way to improve synthesis conditions and the properties of the resulting product is the search for and improvement of reaction initiators and other active additives. It has also been established that grafting maleic anhydride onto polypropylene significantly alters not only its performance properties but also its structure. Maleic anhydride is particularly capable of affecting the crystalline structure of polypropylene and its blends. Traditionally, maleated polypropylene has been effectively used as a compatibilizer for polypropylene-based blends, improving its compatibility with other polyolefins, as well as natural high-molecular compounds and elastomers. Furthermore, a number of studies published in recent years have demonstrated the significant impact of maleated polypropylene on improving compatibility in polymer composites with various fibers and wood-polymer composites. Another area of application for maleated polypropylene is currently actively developing are polymer dielectrics.
