N. Cardi et al., SYNTHESIS AND CHARACTERIZATION OF SYNDIOTACTIC POLYSTYRENE AND POLY[STYRENE-CO-(P-METHYLSTYRENE)], Macromolecular symposia, 102, 1996, pp. 123-130
Syndiotactic polystyrene and copolymers of styrene and (p) under bar-m
ethylstyrene were synthetized in bulk by using a titanium tetraethoxid
e/methylaluminoxane catalytic system. The polymers were analyzed by C-
13 and H-1 Nuclear Magnetic Resonance, Infrared Spectroscopy, Gel Perm
eation Chromatography and Differential Scanning Calorimetry and their
properties were compared.
