KINETICS OF POLYMERIZATION OF ISOPRENE WITH Nd(Opri)2Cl-AlEt3 SOLUBLE CATALYST SYSTEM Ⅰ.A GENERAL KINETIC INVESTIGATION
he kinetics of the polymerization of isoprene with a soluble rare earth catalyst system Nd(OPri)2Cl-AlEt3 has been examined in a specially designed dilatometer.The polymerization process was characterized by a steady-state reaction within the experimental range
and polymerization rate is first order in both the concentration of neodymium compound and monomer
that is
Rp =-d[M]/dt=Kp[Nd][M].The apparent activation energy of isoprene polmerization has been found to be 57.4KJ/mol in heptane.
