Patent AT-E401360-T1: [Translated] POLY(ETHERESTER) POLYOLS AND METHOD FOR THE PRODUCTION THEREOF

Preparation of poly (etherester)n (I) comprises: reaction of a mono or polycarboxylic acid ester containing hydroxy group with an alkyleneoxide to form mono or polycarboxylicacid ester with one or more polyether chains (II) by ring opening; and either transesterification of (II) to give (I) with 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. 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.
