Syndiotactic Polystyrene: Synthesis, Characterization, ...
Syndiotactic Polystyrene (SPS), synthesized in a laboratory for the first time in 1985, has become commercialized in a very short time, with wide acceptance on the global plastics market.

Physical Properties of Polymers Handbook
However, the rationalization of these properties for stereoirregular or syndiotactic
chains was impeded to some extent by the lack of experimental results on
polymer samples with precisely tailored microstructure. In a highly isotactic chain,
the ...

Rafael A. Auras, Loong-Tak Lim, Susan E. M. Selke, 2011
An alternating system is shown in Figure 4.6 (b) which is known as a syndiotactic
structure whilst Figure 4.6 (c) depicts a random system — known as an atactic
structure. Thus the isotactic and syndiotactic structures are regular whilst the ...

Ziegler-Natta Catalysts Polymerizations
Furthermore, if highly syndiotactic polypropylene could be made, physical
chemists would have a polymer available for fundamental studies that could be
made in any degree of isotacticity and syndiotacticity. But how does one alter a
