【Abstract】 The apparent activation energy of chlorosulfonation reaction of chlorinated polyethylene(CPE) was studied for the synthesis reaction of chlorosulfonated polyethylene(CSM) from CPE in the solid state. The change of reaction heat was used to measure the reaction speed. A method was proposed for approximately calculating the apparent activation energy. The result indicated that the apparent activation energy was low( E a=9 12 kJ/mol), and the chlorosulfonation reaction of CPE by solid phase could be carried out at low temperature.更多还原
