Article summary:
1. This article discusses the development of a “quasi-living” insertion polymerization process to create a molecularly characterized isotactic polypropylene-block-polyethylene.
2. The study examines the impact of substituent effects on propylene polymerization in cyclic bis(phenoxyaldimine) titanium catalysts, as well as the morphology of isotactic polypropylene–polyethylene block copolymer driven by controlled crystallization.
3. The article also looks at the 100th anniversary of macromolecular science, copolymerization of propylene with higher α-olefins, and separating electronic from steric effects in ethene/α-olefin copolymerization.
