Compatibilizers, also referred to as coupling agents, are additives, that when added to a blend of immiscible materials during extrusion, modifies their interfacial properties and stabilizes the melt blend. Immiscible blends may be mixtures of two or more dissimilar polymers or mixtures of polymer (s) and organic or inorganic components. One of the most successful techniques for compatibilization is with the use of thermoplastic maleic anhydride graft copolymers.
Compatibilization of polymer blends through the addition of thermoplastic maleic anhydride graft copolymers provides the means to significantly enhance the properties of a melt blend of dissimilar materials. Properties of mixed materials are determined by blend morphology; how one polymer or additive phase disperses and incorporates into another polymer phase. Thermoplastic maleic anhydride grafted copolymers provide a very effective means to alter the dissimilar phases and enhance the physical, thermal and optical properties of a polymer blend. Primary Compatibilizer Markets for thermoplastic maleic anhydride grafted polymers are plastics compounding and mixed plastic recycle industries.
