Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C). Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components.
The 2-6-6-2s could handle more tonnage than the double-headed pair of 2-8-0s they replaced, and they burned less coal in the process. The 2-6-6-2s proved to be ideal mine run engines as their power and flexibility plus low weight on drivers made them ideal for the curving and heavily graded branches in the mountains of Virginia and West Virginia.
PDF has (as of version 2.0) 25 graphics state properties, of which some of the most important are: The current transformation matrix (CTM), which determines the coordinate system; The clipping path; The color space; The alpha constant, which is a key component of transparency; Black point compensation control (introduced in PDF 2.0)

front cover G1 1930. This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – one of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as ...
In the open catalogue project Open Icecat, a separate OCI is defined for the exchange of multimedia data between multilingual product catalogs. The OCI format is used to define the field mapping between the supplier's catalog and the SAP SRM shopping cart, to ensure that the data is transferred accurately and completely between source and receiver.
2,6-DMP is produced by the methylation of phenol. With production >100,000 tons/y, it is the most important xylenol. The methylation is carried out by contacting gaseous phenol and methanol at elevated temperatures in the presence of a solid acid catalyst: [2] [3] C 6 H 5 OH + 2 CH 3 OH → (CH 3) 2 C 6 H 3 OH + 2 H 2 O
