Process for the preparation of crystalline vinylaromatic polymers with a predominantly syndiotactic structure |
| abstract |
Process for the preparation of crystalline vinylaromatic polymers with a predominantly syndiotactic structure which comprises polymerizing vinylaromatic monomers, alone or mixed with at least one other monomer, in the presence of a catalytic system essentially consisting of: n a) a complex of titanium or zirconium selected from those having general formula: n n MR.sub.1 R.sub.2 R.sub.3 R.sub.4, A.sub.1 MR.sub.1 R.sub.2 R.sub.3, A.sub.1 n n A 2 MR 1 R 2 (I) n b) a co-catalyst selected from an alkylalumoxane and a compound of boron having formula (II): n n BX.sub.1 X.sub.2 X.sub.3 (II) n n or one of its salts; n c) a derivative of tin having general formula: n n SnR.sub.5 R.sub.6 R.sub.7 R.sub.8 (III) |
