摘要

In 1929, Staudinger and co-workers predicted a correlation between the physical properties of a polymer and its main-chain stereochemistry. Not until 1947, however, was the first synthetic stereoregular polymer reported. Amid considerable controversy, Schildknecht and co-workers attributed the semicrystalline properties of a poly(isobutyl vinyl ether) to the ordered stereochemistry, or tacticity, of its polymer backbone. In the 1950s, research in the field of stereoregular polymerization gained tremendous momentum when academic and industrial laboratories discovered heterogeneous titanium catalysts for synthesis of semicrystalline isotactic polypropylene. Since these initial discoveries, synthesis of polymers of defined stereochemistry has been actively pursued in both industrial and academic laboratories.
