✦ Synopsis


Los 241amo.~, ,Vew Mexico).

A study has revealed that major differences exist between the physical flroperties of graf'hites manufactured with y-alumina-polymerized furfury. alcohol resin binders and those made with acid-polymerized resins. The causes of these property differences have been directly related to the chemical comf>ositions of the two binder types. Improved graf'hite binder materiafs have resulted from the understanding gained from these studies.

## Two kinds of y-alumina-polymerized furfuryl alcohol resins were synthesized and examined as graphite binder materials. Prior to their use, the resins were characterized according to viscosity and molecular size distribution. Investigation by gas chromatography showed that, relative to acid-pol

The viscosities and molecular size distributions of furfuryl alcohol resin binders are shown to have important influences on the fabrication and physical properties of graphites made from them. Increasing binder viscosity to about 2000 cp improves the physical properties of the graphite. Above this,
