The molecular weight distributions at various milling times measured by GPC show an initial asymmetric broadening and then a gradual returning to the original narrow bell‐shaped distribution. Analysis of molecular weight distributions suggests a preferential chain scission near the chain ends. X‐ray diffraction spectra of isotactic polystyrene samples show that after 24 hr of milling, the semicrystalline polystyrene was completely transformed into an amorphous polymer. DSC thermogram of the milled isotactic polystyrene reveals several crystallization peaks preceding melting when the samples were heated.</jats:p>","journal":"Journal of Applied Polymer Science","year":1981,"id":30181,"datarank":1.2217264193181785,"base_score":2.4849066497880004,"endowment":2.4849066497880004,"self_citation_contribution":0.37273599746820013,"citation_network_contribution":0.8489904218499784,"self_endowment_contribution":0.37273599746820013,"citer_contribution":0.8489904218499784,"corpus_percentile":null,"corpus_rank":null,"citation_count":11,"citer_count":11,"citers_with_citation_signal":10,"citers_with_endowment":10,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":164564,"name":"Hiroyasu Nomura","orcid":null,"position":1,"is_corresponding":false},{"id":164565,"name":"Yutaka Miyahara","orcid":null,"position":2,"is_corresponding":false},{"id":164563,"name":"Somsak Vivatpanachart","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.4849066497880004,"endowment":2.4849066497880004,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998881","pmcid":null,"openalex_id":"https://openalex.org/W2054160367","authors":[],"funders":[],"total_grants":0,"fwci":0.5068,"citation_percentile":0.59800061,"influential_citations":0,"citation_trend":[{"year":2018,"count":1},{"year":2020,"count":1},{"year":2024,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fapp.1981.070260505","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/app.1981.070260505","host_type":"publisher"},{"url":"https://doi.org/10.1002/app.1981.070260505","host_type":"journal"}],"fields_of_study":["Polymer crystallization and properties","Polymer Nanocomposites and Properties","biodegradable polymer synthesis and properties","Materials Science"],"mesh_terms":[],"keywords":["Tacticity","Polystyrene","Materials science","Crystallinity","Amorphous solid","Polymer","Crystallization","Molar mass distribution","Polymer chemistry","Ball mill","Chemical engineering","Composite material","Crystallography","Polymerization","Chemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-09T01:57:58.885066Z","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":[]}
