摘要：
The modification of poly(ethylene-co-octene) (POE) by grafting maleic anhydride (MAH) and reacting with amino-silicone oil (PDMS-NH2) was conducted to form partially crosslinked POE (POE-PDMS) with branched structure for solving the problem of easy cell rupture in the foaming process of POE, and microcellular foaming of POE-PDMS was carried out with supercritical carbon dioxide as foaming agent. The foaming behavior and compressive property of the modified POE by polydimethylsiloxane (PDMS) were systematically investigated. The results showed that the introduction of PDMS could greatly increase the melt strength, improve the solubility of carbon dioxide and foaming property, and broad the range of foaming temperature. The microcellular foaming material of POE-PDMS with cell density of 1.76×109 cells∙cm-3 and average cell diameter of 7.3 μm was obtained, and its compressive strength was also improved. © 2022, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
