A syndiotactic poly-p-methyl-styrene in powder form is prepared according to the method described in Macromolecules, 1989, 22, 104. p-Methyl-styrene (0.5 mmoles) is polymerized in toluene (59 ml) at 50° C. for 24 hours, in the presence of tetrabenzyltitanium (5·10 moles) and methylalumoxane (0.3 g); 8.5 g of s-PpMS are obtained. A film about 100 microns thick is produced by compression molding at a pressure of 2 Kg/cm2 and at a temperature of 230° C. An amorphous film is thus obtained.
