Synthesis of polyisoprene macromonomer having terminal vinyl group and copolymerization of the macromonomer with ethylene and propylene

Autor: Yutaka Takakura, Kazunobu Senoo, Kiyoshi Endo

Publikováno v: European Polymer Journal. 35:1413-1417

Synthesis of polyisoprene macromonomer having terminal vinyl group and graft copolymerization of the macromonomer with ethylene and propylene was investigated. The polyisoprene macromonomer having terminal vinyl group (VIPM) was synthesized by a reac

Investigation of Effects of Additive for ATF and Test Condition on Pitting Life of Gear Tooth in the FZG Pitting Test

Autor: Yutaka Takakura, Susumu Matsumoto, Toshihiko Ichihashi

Publikováno v: ASME/STLE 2011 Joint Tribology Conference.

The reduction in viscosity of Automatic Transmission Fluids (ATFs) for improving fuel economy results in a reduction in transmission gear fatigue life due to occurring pitting. The aim of this study is to establish a suitable test condition for evalu

Autor: Tatsuya Kawabe, Hideo Morita, Yutaka Takakura

Publikováno v: NIPPON SHOKUHIN KOGYO GAKKAISHI. 40:881-887

Prevention of the caking of KCl-NaCl powder produced by a spray-dryer was investigated. The spray-dried powders of both a simple KCl-NaCl mixture and a mixture of KCl and NaCl with an amino acid that was less soluble than KCl and NaCl and that had hy
