In polymerization, {2,6- i Pr2-C6H3N˭C(CH3)-(CH3)C˭N- i Pr2-C6H2}NiBr2(CatA) and {2,6-Me2-C6H3N˭C(CH3)-(CH3)C˭N-Me2-C6H2}NiBr2(CatB) was adopted to yield branched and hyperbranched segments via chain walking polymerization at one ethylene atm and 20°C, respectively. Then the chain transfer agent(ZnEt2) facilitated chain transfer between two active metal centers to accomplish chain shuttling polymerization of ethylene. This strategy stands out from “living”/controlled polymerization and coupling block polymers techniques for just using ethylene as monomer, carrying out under moderate polymerization and obtaining the resultant polymer with novel microstructure.","is_dataset_classified":null,"base_score":2.3978952727983707,"endowment":2.3978952727983707,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26207759","pmcid":null,"openalex_id":"https://openalex.org/W2005249175","authors":[],"funders":[],"total_grants":0,"fwci":0.4157,"citation_percentile":0.58460109,"influential_citations":0,"citation_trend":[{"year":2017,"count":2},{"year":2019,"count":2},{"year":2020,"count":2},{"year":2021,"count":2},{"year":2023,"count":1},{"year":2024,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://www.tandfonline.com/doi/pdf/10.1080/03602559.2014.935409","host_type":"publisher"},{"url":"https://doi.org/10.1080/03602559.2014.935409","host_type":"journal"}],"fields_of_study":["Dendrimers and Hyperbranched Polymers","Polymer Surface Interaction Studies","Fuel Cells and Related Materials"],"mesh_terms":[],"keywords":["Chain transfer","Polymerization","Living polymerization","Polyolefin","Polymer chemistry","Chain-growth polymerization","Polyethylene","Kinetic chain length","Chemistry","Living free-radical polymerization","Monomer","Reversible addition−fragmentation chain-transfer polymerization","Ethylene","Materials science","Polymer","Radical polymerization","Organic chemistry","Catalysis"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-18T21:58:24.240553Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
