Design of stereoselective Ziegler-Natta propene polymerization catalysts. [PDF]
Proc Natl Acad Sci U S A, 2006 After five decades of largely serendipitous (albeit formidable) progress, catalyst design in Ziegler–Natta olefin polymerization, i.e., the rational implementation of new active species to target predetermined polyolefin architectures, has ultimately become a realistic ambition, thanks to a much deeper fundamental understanding and major ...
