| Abstract: | Chain transfers in the polymerization of butadiene with Ni(naph)_2-Al(i-Bu)_3+Me-■- (BF_3OEt_2+n-C_8H_(17)OH) (called Ni-Al-B) catalyst system have been investigated. It is found that there exist only transfers to monomer (Bd) and boron compound (B), and that the apparent activation energy for the chain propagation is 32.9 KJ.mol~(-1). The drgree of polymerization equation in the system can be written as follows; |
