Preparation of poly (etherester)n (I) comprises: reaction of a mono or polycarboxylic acid ester containing hydroxy group of formula ((R-O-(C=O)-) m-R-a-(-OH) n) with alkyleneoxide to form mono or polycarboxylicacid ester with one or more polyether chains (II), by ring opening, where the alkylene oxyaddition takesplace optionally in the presence of di- or polyols and dicarboxylic acid esters; and either transesterification of (II) to give (I) with hydroxy groups, where the transesterification takes place optionally by the addition of di- or polyols, diol and dicarboxylic acids, dicarboxylic acid derivatives, monocarboxylic acid esters or monocarboxylic containing di- or polyols or hydroxy groups; or reaction of (II) with mono or polycarboxylicacidester containing free hydroxy group to give (I) with ester; or hydrolyzation of (II) with mono or polycarboxylic acid containing free hydroxy group to give (I) with carboxylic acid. R : monovalent aryl-, alkyl-, aralkyl-, alkenyl- or alkynyl- radical; and R-a : bivalent aryl-, alkyl-, aralkyl-, alkenyl- or alkynyl- radical. Provided that: if m is 1, then n is1; or if m is >= 2, then n is 1; or if n is >= 2, then m is1. Independent claims are included for: (1) a poly(etherester), which is prepared by the above procedure; and (2) use of (I) for the preparation of polyurethane materials.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the complete Patent AT-E401360-T1: [Translated] POLY(ETHERESTER) POLYOLS AND METHOD FOR THE PRODUCTION THEREOF on the official website.", "downloadURL": "https://pubchem.ncbi.nlm.nih.gov/patent/AT-E401360-T1", "mediaType": "text/html", "title": "Official Data Source"}], "identifier": "https://healthdata.gov/api/views/pb8n-c636", "issued": "2025-09-05", "keyword": ["chemistry", "innovation", "patent", "pubchem", "research"], "landingPage": "https://healthdata.gov/d/pb8n-c636", "modified": "2025-09-06", "programCode": ["009:066"], "publisher": {"@type": "org:Organization", "name": "National Center for Biotechnology Information (NCBI)"}, "theme": ["NIH"], "title": "Patent AT-E401360-T1: [Translated] POLY(ETHERESTER) POLYOLS AND METHOD FOR THE PRODUCTION THEREOF"}
