Abstract: Complexable polymeric binder-lubricant blends are disclosed for production by powder metallurgy techniques of ferrous compositions with remarkably high green strength upon compaction, or soft magnetic ferrous powder/resin composites with improved processability and magnetic properties. An exemplary composition consists of a ferrous powder, a thermoset phenolic resin and poly(ethylene oxide), both polymers exhibiting, when intimately mixed, strong intermolecular acid-base interactions giving rise to an interpolymer complex which imparts a high strength to the resulting ferrous powder compact.

Abstract: There is described a process for producing hydrocarbon products in the diesel boiling range, comprising mainly C.sub.15 -C.sub.18 paraffins and being highly effective as diesel fuel ignition improvers. The process comprises hydroprocessing vegetable oils such as canola, sunflower, soybean and rapeseed oils or some fatty acids in hydroprocessing temperatures (350.degree.-450.degree. C.), pressures (4.8-15.2 MPa) and liquid hourly space velocity (LHSV) of 0.5-5.0 hr.sup.-1 depending on the type and purity of the feedstock. Commercially available hydroprocessing catalysts may be used.
