Abstract: In the production of stretch Oriented poly(hydroxycarboxylic acid) filaments suitable for use in medical products (e.g. sutures), high speed production is achievable by application, prior to the drawing step, of a lubricant which minimizes filament breakage and facilitates the use of draw ratios of at least 2:1, more typically at least 5:1.

Abstract: Compounds that are themselves effective cetane improvers in diesel fuel but are considered too explosion sensitive for safe handling can be rendered relatively nonsensitive by blending with nitric acid esters of bicyclic or tricyclic alcohols containing a four-membered or five-membered ring and the resulting blend is an effective cetane improver. An example is a 50-50 blend of 2-methyl-2-nitropropyl nitrate, a shock-sensitive compound, with 5,6-cyclopenteno-2-norbornyl nitrate to give a relatively insensitive, but very effective cetane improver.
