Polypropylene (PP) is a remarkably versatile thermoplastic polymer, lauded for its lightweight nature, excellent chemical resistance, and ease of processing. However, its inherent non-polar character can limit its compatibility with other polar polymers and fillers, thereby restricting its use in certain advanced applications. This is where Maleic Anhydride (MAH) comes into play, transforming polypropylene into a more functional material through grafting.

The process of grafting Maleic Anhydride onto polypropylene, often referred to as maleic anhydride for polypropylene modification, involves reacting polypropylene with MAH, typically in the presence of a peroxide initiator. This reaction creates free radicals on the polypropylene chains, which then covalently link with MAH. The result is a modified polypropylene with enhanced properties, particularly improved interfacial adhesion and compatibility with a wider range of materials.

This modification is crucial for several industrial sectors. In the automotive industry, Maleic Anhydride-modified polypropylene can be used for interior and exterior components, enhancing impact resistance and paint adhesion. In construction, its improved compatibility with fillers like glass fibers or minerals allows for the creation of stronger, more durable composite materials. This demonstrates the broad utility of maleic anhydride as a performance enhancer.

The introduction of polar anhydride groups from the grafted MAH significantly improves the interaction between the polypropylene matrix and polar fillers or other polymers. This enhanced adhesion is key to achieving superior mechanical properties and better dispersion of additives.
