wOrtc concerning tb* original cwplnlntlast Moveaber, we weds up the
naphtha solution ae described in the above aewo end observed results. The
results were an imediats precipitation of crystals la tv lays froa the
cKOatlOn Containing: Arcelor 4465 having a softening point ov^r 64**5* Aroolor
4465 having a softening point between 62-64 threw dosn. a eodiraent in four to
eight days. The solutions ade with Aroolor 4465 of softening point 60-62fe*

The above observations led to out reOCRnendation that the,softening point be
lowered on Aroolor'4465 to include the temperatures 56-62C* ~

A saaple of the special tot 540 of Aroolor 4465 with a softening point of 56.2C. has been standing in the soltent solutSon for throe oaths without a trace of sediment*
For your information the precipitation of a sediment when Aroolor 4465 is
dissolved In oat aliphatic solvents Is by no means something new* A re- -. ^

Before establishing those tests* it would be wise to ascertain the es&et
