Effect on the Impact Properties of Adding Long‐Chain Branched Polypropylene in Polypropylene‐Polyolefin Elastomer Cellular Polymers Produced by Core‐Back Injection Molding

Different blends of a linear polypropylene (L-PP), long-chain branched (LCB-PP), and polyolefin elastomer (POE) are prepared foamed using core-back injection molding. The objective is to analyze the use POE LCB-PP as complementary strategies improve cellular polymers’ impact response. parameters then studied in molded plaques understand samples’ mechanical behavior. Parameters such interfacial tension, morphology, extensional rheology, structure, crystallization behavior characterized detail. addition allows improving response both solids polymers, but stiffness reduced. On other hand, substitution L-PP by LCB-PP, containing POE, results materials with better properties, due different crystalline morphology comprising samples, orientation, thicker solid skin.
