POLYMERIZATION REACTION KINETICS OF OCTADECYLACRYLATE

A polymer of octadecyl acrylate has been synthesized in solution and the effect of initiator, monomer, temperature and solvent on the polymerization reaction rate has been studied. Results have shown that the reaction rate is in direct proportion to the first power of monomer concentration and a half power of initiator concentration. Polymerization reaction constant factor Aa is 123.4, the activity energy Ea is 29.72?KJ/mol. The type of solvent has little influence on the polymerization rate and there is no accelerating polymerization. The order of chain transfer constant of four solvents is:CCl 4CHCl 3(CHCl 2) 2C 6H 5CH 3.
