Polypropylene/poly(butyl methacrylate) blends prepared by diffusion and subsequent polymerization of butyl methacrylate in isotactic polypropylene pellets

Polypropylene/poly(butyl methacrylate) (PP/PBMA) blends were prepared by diffusion and subsequent polymerization of butyl methacrylate (BMA) in commercial isotactic polypropylene (iPP) pellets. The diffusion kinetics, diametrical distribution of PBMA in a pellet and phase morphology of a typical PP/PBMA blend were investigated.
