Procedure

In this experiment, a 30/70 isoprene-butadiene rubber (IBR) was prepared using a preformed catalyst described in Example 2. The procedure described in Example 3 was utilized in this examples except that a premix containing a 30:70 mixture of isoprene and 1,3-butadiene was used as the monomers. GC analysis of the residual monomer indicated that 90 percent of monomers were consumed after 9 minutes. The polymerization was continued for an additional 21 minutes.
