A functional fluid composition is provided which comprises a plurality of different phosphazene compounds of the general formula (P=N).sub.n (R).sub.a (R').sub.b (R').sub.c (R'').sub.d wherein R is at least one alkoxy moiety described by the general formula --OCH.sub.2 (CF.sub.2).sub.y X, with X being hydrogen or fluorine and y being equal to 1 to about 10; R', R' and R'' are different aryloxy moieties, each of R', R' and R'' being selected from the group consisting of phenoxy, alkoxy phenoxys, alkyl phenoxys, chlorinated phenoxys, fluorinated phenoxys, aryl phenoxys, phenoxy phenoxys, fluoroalkyl phenoxys, fluoroalkoxy phenoxys, chlorinated phenoxy phenoxys, fluorinated phenoxy phenoxys and mixtures thereof; n is equal to 3 to about 4 for each of said phosphazene compounds, each of a, b, c and d is equal to or greater than zero such that the sum a+b+c+d is equal to 2n; and for the composition as a whole, the average value of each of a, b, c and d is greater than 0.

Phosphazene based functional fluid compositions

A process for the preparation of certain phosphazene esters. The process is characterized by its utilization of a phase transfer catalyst, which may be either a quaternary ammonium compound or a quaternary phosphonium compound.

Process for preparation of phosphazene esters

Trityl compounds wherein a triphenylmethyl group is attached to oxygen, divalent sulfur, trivalent nitrogen or a halogen are effective synergists for organic bromine flame retardants in polypropylene compositions.

Flame retardant polypropylene compositions containing trityl synergists

Improved nucleate boiling cavities are provided in a heat exchange surface by mechanically forming indentations on the heat transfer surface and then electrodepositing a metal on the pitted surface at a high current density followed by strengthening at lower current densities. Also described is a method of transferring heat from a warm fluid to a boiling liquid utilizing the improved nucleate boiling structure.
