## 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
Several series of furfuryl alcohol resins, made by the polymerization of furfuryl alcoho with a variety of catalysts and having viscosities as high as 7 X 108 cpoise, were characterized by gel permeat.ion chromatography (GPC). A series-by-series comparison of the GPC curves of the resins was made, t
Proton CW and pulse NMR studies for furfuryl alcohol resin carbonized over the temperature range 60-86O"C are performed. The results are interpreted in terms of structural and chemical changes taking place during heat treatment. Heating up to: (i) 240°C results in an increase in molecular weight and
## Abstract Furfuryl alcohol resins contain a broad spectrum of compounds. The distribution of these compounds in a given resin varies with the manufacturing conditions. A resin containing a high proportion of low molecular weight constituents has been prepared and separated into fractions. Twelve
