Staudinger predicted a correlation between the physical properties of a polymer and its main-
chain stereochemistry as early as 1929. 1 However it was not until 1947 that Schildknecht …

Polyolefin plastics are widely used due to their low cost and outstanding properties, but their
environmental persistence presents a major societal challenge. Polyhydroxyalkanoates …

Polyhydroxyalkanoates (PHAs), such as poly [(R)-3-hydroxybutyrates][(R)-P3HB], are
produced by bacteria and are promising alternatives to nondegradable polyolefin plastics …

Crystalline polymers may be affected by various kinds and amounts of structural disorder.
Lackof order in polymer crystals may arise from the presence of defects in the chemical …

The cyclopolymerization of α, ω-dienes catalyzed by transition metals (TMs) is one of the
most attractive synthetic routes for the production of cyclic polyolefins (COPs). These COPs …

Despite recent progress made toward the development of catalysts that can mediate the
living Ziegler-Natta polymerization of R-olefins, 1 their use for the production of well-defined …

The precise use of a widely available and inexpensive metallocene catalyst enabled the
synthesis of isotactic polypropylene copolymers characterized by the copresence of …

Chiral Salan ligands were found to wrap in a highly diastereoselective manner around
zirconium leading to C 2-symmetric complexes of predetermined chirality at the metal. These …

Ring-opening metathesis polymerization (ROMP) of norbornene with most catalysts
produces a polymer with an atactic placement of the cyclopentylene rings, yet partial …

The crystal structures of highly crystalline isotactic and syndiotactic hydrogenated poly
(norbornene) s [H-poly (NB) s], synthesized by the stereospecific ring-opening metathesis …
