Most plastic products consist of two or more polymers. Properties of packaging films,
coextruded profiles, and toughened plastics are achieved via combining immiscible
polymers. Controlling adhesion at the interface is critical to optimizing their
performance. We show interfacial reactions between polylactide and polyethylene form
block copolymer (i.e., reactive compatibilization), improving interfacial adhesion and
blend toughness. Small levels of catalysts accelerate the reaction rate, especially when
catalyst locates at the interface. This general approach reduces the required amount of
expensive functional polymers, and extends the variety of reactions available for reactive
compatibilization.
