ABSTRACT
Their additives were miscible in the styrenic phase and were reactive in the nylon phase. The reactive additives were SAN/SMA copolymers of co-monomer composition appropriate for establishing the requisite miscibility. The anhydride functional groups of these copolymers can react with primary amine groups, as occur in the polyamide phases. High-quality dispersions and good physical properties are achieved, although the economic consequences of this strategy make it uncompetitive in the marketplace. George et al. report (see Figure 6.8) that addition of phenol, under proper conditions, can lead to the creation of diblock copolymers at the interfaces in alloys of polypropylene and NBR elastomer [9]. DiLorenzo and Frigione published a helpful review of the work involving self-compatibilization in reactive pairs [14].
