This compilation opens with a distinct perspective on the solubility of maleic anhydride, presenting the research findings regarding the identification of the most suitable solvent selection for systems containing maleic anhydride. A survey of more recent developments with particular emphasis on the past 10 years is also provided. The authors review maleic-anhydride-polypropylene as compatibilizer in polypropylene nanocomposites with various types of nanofillers such as clay, carbon nanotube, graphene and metal oxide, focusing on their preparation, properties and performance.
