Improved Mechanical Properties of Compatibilized Polypropylene/Polyamide-12 Blends
International Journal of Polymer Science, 2015 Compatibilized blends of polypropylene (PP) and polyamide-12 (PA12) as a second component were obtained by direct injection molding having first added 20% maleic anhydride-modified copolymer (PP-g-MA) to the PP, which produced partially grafted PP (gPP).
