Static and dynamic mechanical properties of flame‐retardant copolyester/nano‐ZnCO3 Composites

15-Sep-2011 | Liu, Haiming; Wang, Rui; Xu, Xi, Journal of Applied Polymer Science, 2011

Abstract Novel phosphorus‐containing copolyester nanocomposites were synthesized by in situ polymerization with 2‐carboxyethyl(phenylphosphinic) acid (CEPPA) and nano‐ZnCO3. The flame retardancy and static and dynamic mechanical properties of poly(ethylene terephthalate) (PET)/nano‐ZnCO3 ...

Preparation of polybutene‐1/multiwall carbon nanotube composite by oxidation and limonene radical grafting and its characterization

27-Jun-2011 | Nakatani, Hisayuki; Ogura, Masashi; Yoshikawa, Takanori; Miyazaki, Kensuke; Okazaki, Noriyasu; Terano, Minoru, Polymer International, 2011

Abstract In this study, a novel preparation of a polybutene‐1 (PB) and multiwall carbon nanotube (MWNT) composite was achieved by a combination of PB autooxidation and a radical grafting reaction using an Nd2O3/dicumyl peroxide (DCP) radical initiator system with limonene. The autooxidation ...
