High density polyethylene gas pipes are plastic pipes used to transport gas, liquefied gas, and natural gas. This type of plastic pipe has excellent low temperature resistance, chemical corrosion resistance, and good electrical insulation performance; Compared with low-density polyethylene pipes, they ...
The copolymers are particularly useful in film applications showing an excellent balance of processing, optical and mechanical properties. The novel polymers may suitably be prepared in the gas phase in the presence of metallocene complexes.doi:US6642339 B1Choon Kooi Chai...
Evaporation of metastably spin-polarized solid H{sup {up arrow}}D or o-{sup {up arrow}}D provides polarized {sup {up arrow}}D gas sources which can serve as internal polarized targets of densities substantially higher than are currently ... A Honig 被引量: 2发表: 1989年 Spin density ...
The effect of the density-dependence in the effective interaction for (3He, d) reactions has been examined. It is found that inadequacies of the DWBA description of these reactions, particularly those using the shallow potentials for 3He, are largely overcome by taking account of the density-de...
This article describes the solubility of carbon dioxide, ethylene and propane in 1-octene based polyethylene of 0.94, 0.92, 0.904, and 0.87 densities. The isotherms obtained in the gas sorption experimental device display a sorption behavior similar to that of glassy polymers. We apply the dual ...
