Most specificly, it relates to an activated, substantially water soluble poly(ethylene glycol) having a linear or branched poly(ethylene glycol) backbone and at least one terminus linked to the backbone through a hydrolytically stable linkage, wherein the terminus is branched and has proximal reactive groups is reacted with active moieties in a biologically active agent such as a protein or peptide thus forming conjugates between the activated poly(ethylene glycol) and the biologically active agent.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E399809-T1: [Translated] METHOD FOR PRODUCING POLYMER CONJUGATES on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E399809-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/36sp-w9pn", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/36sp-w9pn", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E399809-T1: [Translated] METHOD FOR PRODUCING POLYMER CONJUGATES"}
