Abstract: | The kinetics of thermal degradation of three phenolir resins which ratio of formaldehyde and phenol are differnet have been studied by thermal-grarimery. When the mol ratio of formaldehyde and phenol is 1.81 the phenolic resin has the highest activation energy of heat degradation and the best heat restantance. |

Keywords: | phenolic resin thermal degradation kinetics active energy |
