Compatibilization of PP/PS Blends via a Novel Acylation Reaction

In the present work, Friedel-Crafts acylation reaction was used to compatibilize PP/PS blends. Rheology and morphology of different blends were considered in conjunction with FTIR analysis. It was found that in the presence of AlCl3 and PP-g-MA the acylation reaction is taken place at the interface and results to formation of compatibilizer copolymer which reduced the interfacial tension and hence particle size of dispersed PS phase.
