Munoz-Pascual, Santiago published the artcileEffect on the Impact Properties of Adding Long-Chain Branched Polypropylene in Polypropylene-Polyolefin Elastomer Cellular Polymers Produced by Core-Back Injection Molding, Product Details of C42H63O3P, the publication is Macromolecular Materials and Engineering (2021), 306(4), 2000728, database is CAplus.
Different blends of a linear polypropylene (L-PP), a long-chain branched polypropylene (LCB-PP), and a polyolefin elastomer (POE) are prepared and foamed using core-back injection molding. The objective is to analyze the use of POE and LCB-PP as complementary strategies to improve cellular polymers’ impact response. Different parameters are then studied in blends and injection molded plaques to understand the samples’ mech. behavior. Parameters such as the interfacial tension, elastomer morphol., extensional rheol., cellular structure, and crystallization behavior are characterized in detail. The addition of POE allows improving the impact response of both the solids and cellular polymers, but the stiffness is reduced. On the other hand, the substitution of L-PP by LCB-PP, in blends containing POE, results in solids and cellular materials with both better stiffness and better impact properties, due to the different crystalline morphol. comprising the samples, a different cellular orientation, and thicker solid skin.
