Controlling the Stereoregularity of Polyacrylonitrile and Its Determination Using Small-Molecule Host Inclusion Compounds
This research focuses on synthesizing highly stereoregular polyacrylonitrile (PAN) and determining its tacticity (predominantly isotactic or syndiotactic), utilizing guest monomer (acrylonitrile = AN) host inclusion polymerization. Highly stereoregular PAN, with a meso or racemic diad content ~ …

An investigation into thermally induced structural modifications in isotactic polypropylene and its blends with amorphous terpolymers
… to be highly dependant on molecular weight and stereoregularity.<br/><br/>Solvent extraction of a particular commercial polypropylene sample yielded fractions which, when characterised by GPC and <sup>13</sup>C-nmr, clearly showed that fractionation had been achieved on the basis of molecular …

Accessing Model, Functional Polyolefins and Polyolefin Copolymers with Ring-Opening Metathesis Polymerization
… Chapter 4 discusses the additional effects of stereoregularity on the properties of a similar EVOH polymer. Appendix B describes the attempted synthesis of a disubstituted ROMP monomer for the synthesis of EVOH copolymers containing a higher vinyl alcohol copolymer content compared to the …

Radical based molecular design of discrete and stereoregulated oligomers via photomediated RAFT single unit monomer insertion (photo-RAFT SUMI)
… the polymer chain: monomer sequence and stereoregularity. For a long time, polymer chemists have dedicated themselves to achieve such dual control during the synthesis of synthetic polymers in order to emulate such structurally perfect biopolymers. Despite the success of directly …
