Studies on Structures and Dynamic Properties of Peroxide-Crosslinked EPDMs, Part 5 Relation of Storage Modulus to Crosslinking Density and Molecular Mobility Hitoshi IWABUKI Kazuya NAGATA Industrial Technology Center of Okayama Prefecture, Okayama , Japan Toru NOGUCHI Nissin Kogyo Co., Ltd., Toumi-shi, Nagano, Japan Eisuke YAMADA Aichi Institute of Technology, Yakusa-cho, Toyota, Japan Nippon Gomu Kyokaishi,(2006),79(12),551-556 Original Paper in Japanese Abstract Peroxide-crosslinked EPDMs were examined by dynamic mechanical analysis. In a rubbery state, a plot of storage modulus (E') vs. temperature gave an approximately linear relationship. The slope of the approximated line increased with an increase in apparent crosslinking density (ƒË ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() (Received on June 7, 2006) (Accepted on October 3, 2006) Keywords: EPDM, Peroxide, Dynamic Viscoelasticity, Storage Modulus, Crosslinking Density, Pulsed NMR, Spin-spin Relaxation Time, Molecular Mobility |
