Furthermore, the invention relates to a process for the production of a polymer composition comprising: n(i) a step in which ethylene monomers, and optionally further alpha-olefin-comonomers, are polymerised in liquid phase in the presence of a polymerisation catalyst, n(ii) a step in which ethylene monomers, and optionally further alpha-olefin comonomers, are polymerised in the gas phase in the presence of a polymerisation catalyst, and n(iii) obtaining a polymer resin powder after the final polymerisation step wherein the powder has a particle size distribution PSD 95/5  equal to or smaller than 12.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E401357-T1: [Translated] POLYETHYLENE RESIN WITH Narrow grain size distribution on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E401357-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/vc9t-7yth", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/vc9t-7yth", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E401357-T1: [Translated] POLYETHYLENE RESIN WITH Narrow grain size distribution"}
