Fast Analytics of High-Impact Polypropylene (HIPP)

High-impact polypropylenes (HIPPs) are complex blends, featuring a crystalline isotactic polypropylene matrix and dispersed phase consisting of an amorphous ethylene/propylene copolymer (EPR). The relative amount EPR its composition heavily affect the application properties material need to be accurately controlled. Standard analytical methods time- labor-intensive require considerable amounts sample toxic solvent, xylene. Here, we introduce approach HIPP characterization based on crystallization elution fractionation. is fast, can operated just few mg sample, does not sophisticated expensive techniques.
