Wright (1514011) Peter Scott (1589101) Polyolefins Copolymers Migrated from ePrints A new metallocene-based polymerization mechanism is elucidated in which a zirconium hydride center inserts α-methylstyrene at the start of a polymer chain. The hydride is then regenerated by hydrogenation to release a polyolefin containing a single terminal α-methylstyrenyl group. Through the use of the difunctional monomer 1,3-diisopropenylbenzene, this catalytic hydride insertion polymerization is applied to the production of linear polyethylene and ethylene–hexene copolymers containing an isopropenylbenzene end group. Conducting simple radical polymerizations in the presence of this new type of macromonomer leads to diblock copolymers containing a polyolefin attached to an acrylate, methacrylate, vinyl ester, or styrenic segments. The new materials are readily available and exhibit interfacial phenomena, including the mediation of the mixing of immiscible polymer blends.<br><br>Materials synthesized for this work are split into two tables, Table 1 for macromonomers containing Runs 1-12 and Table 2 for block copolymers containing Runs 13-25. The data supplied, i.e. NMR, GPC, DSC, DLS, tensile data and SEM, is organised into folders labelled with the relevant method of characterisation; the folders relating to methods of characterisation that have been conducted on samples contained in both Tables 1 and 2 e.g. NMR, GPC, DSC have also been split into folders labelled Macromonomers, Table 1 and PE-b-PX Copolymers, Table 2. All accompanying data files are labelled according to the material they correspond to e.g. PE-i-DIB, the run number e.g. Run 10 and the table that contains the run e.g. Table 1. Example: All data relating to the PE-i-DIB sample Run 10 in Table 1 will have the file label: PE-i-DIB, Run 10, Table 1. 2018-09-27T00:00:00Z Dataset Dataset 10.82444/warw.33767545.v1 https://figshare.com/articles/dataset/Data_for_Polyolefin_polar_block_copolymers_from_versatile_new_macromonomers/33767545 CC BY 4.0
