## On pyrolysis of a phenol-formaldehyde resin at temperatures up to 700ยฐC there was no change in the infra-red spectrum below 300ยฐC but above this temperature the hydroxyl absorption began to decrease. This and other changes indicated the formation of diphenyl ether type linkages between benxene
Cured samples of a nitrogen-containing acetylene-terminated resin, N,N'-( 1,3-phenylenedimethylidene) bis( 3-ethynylaniline), have been heated at lO"C/min up to 900ยฐC in a pyroprobe attached to a gas chromatograph/mass spectrometer (GC/MS) . Analysis of the volatiles evolved during heating identifie
