A new series, Tribol NC-X fluids, has been introduced by Pfizer Ltd to increase their range of synthetic lubricants. The base fluids of this series are chemically identical to those of the NC series, made available at the start of 1967, but the addition of 0.5% of specially selected oxidation inhibitor gives the fluids improved high temperature stability.

Ahstraet-Copolyethers were prepared by ring-opening polymerization of two oxiranes, ethylene oxide (EO) and ally1 glycidyl ether (AGE), in a high-pressure reactor vessel. The random distribution of AGE units in the copolymers prepared by an anionic route, results in a marked decrease. of the crystal
