反応手順
The polymerization conditions of Example 5 were substantially repeated using the bis(diphenyltrimethylsilylmethyl)titanium (II) complex (0.01 M in toluene), and MAO (1.6 M in toluene), dimethylanilinium tetrakispentafluorophenylborate (DMATB) (0.002 M in toluene), or tris(pentafluorophenyl)borane (borane) (0.01 M in toluene) cocatalyst. Styrene monomer, vinylcyclohexane (VCH) or 4-vinylcyclohexene (4-VCH) were polymerized. The resulting styrene polymers possessed crystalline melting points in excess of 260° C., indicating that the polymers were syndiotactic. Molar ratios of reactants and results are contained in Table IV.
