The thermal decomposition behavior of four kinds（annotated as 1—4） of phenolic-typed polymeric beads,which were synthesized by varying different ratio of 2-phenoxyethanol to formaldehyde（1∶2,1∶3,1∶4,1∶5）,were investigated by using thermogravimetric analysis and the model of Ozawa.The kinetic activation energies of thermal decomposition of the samples of 1—4 were 122.29,162.65,130.76 and 121.40 kJ/mol,respectively.The optimal mole ratio of 2-phenoxyethanol to formaldehyde was 1∶3.
