mixtures of novolac resin with pressed cottonseed in different proportions after their curing as small cylinders, and also pressed cottonseed as powder were pyrolyzed to 1000 $degree$ c. the weight losses of the samples are much higher, up to 500 $degree$ c, while small weight losses are observed over 800 $degree$ c. the weight losses for the 100 pressed cottonseed during the carbonization are essentially higher than those of the specimens also containing novolac; indeed, for the total weight losses up to 1000 $degree$ c an increasing linear dependence was found with increasing proportion of the cottonseed in its mixture with novolac. the shrinkage of the specimens also containing novolac follows in general a curve similar to that of the weight losses for the corresponding case.
