B1R is a maleic anhydride functionalized high molecular weight polypropylene with high reactivity. B1R modifier is designed to offer a way to solve the low combination between different polymer films, like PP/PA co-extruded films, PP/EVOH co-extruded films, and other multilayers films. The strong polar group MAH is grafted onto the molecular chain of B1R, which has reactivity and strong polarity. The addition of B1R can increase the adhesion of different polymer layers, metals, and others.
