PP / EPDM-g-GMA blends Morphology and Mechanical Properties

PDM-g-GMA content increases. PP / EPDM-g-GMA elongation at break of blends with EPDM-g-GMA content increases, the EPDM-g-GMA content of 18 reached the maximum. Therefore, temperature, and EPDM-g for a set of a flood. PP - principle, process and technology [M]. Beijing: China Petrochemical Press,[link widoczny dla zalogowanych], 2002. Zhao.
