Abstract

Official abstract text for this publication.

The invention relates to polyoxyalkylenes having pendant long-chain acyloxy radicals and to a process for preparation thereof by an alkoxylation reaction using double metal cyanide (DMC) catalysts.

First claim

Opening claim text (preview).

The invention claimed is: 1. A polyoxyalkylene of formula (I) A[—O—(CH 2 —CHR—O—) n —(CH 2 —CH(CH 2 OZ)—O—) m1 —(CH 2 —CH(CH 2 Cl)—O—) m3 —(CH 2 —CH(CH 3 )—O—) o —H] a   (I) where A is hydrogen or an organic radical derived from an organic starter compound selected from the group consisting of monohydric monomeric alcohols, polyhydric monomeric alcohols, oligomeric alcohols, and polymeric alcohols, R is independently hydrogen, an alkyl group comprising 2-18 carbon atoms or a phenyl radical, Z is a radical of an organic acid of formula —C(═O)—Z E where Z E is an organic radical selected from the group consisting of linear or branched, saturated or unsaturated aliphatic hydrocarbyl radicals having 7 to 22 carbon atoms or aromatic hydrocarbyl radicals having 6 to 21 carbon atoms, m 1 is a number of 1 to 50, m 3 is 0, n is a number of 0 to 200, o is a number of 1 to 1000, and a is a number of 1 to 8; wherein the polyoxyalkylene does not comprise a terminal structural unit comprising an acyloxy radical; wherein the polyoxyalkylene does not include a methylidene group; where the polyoxyalkylene does not comprise a halogen atom. 2. The polyoxyalkylene according to claim 1 , which has a weight-average molar mass of 400 to 50 000 g/mol. 3. An interface-active polymer, comprising the polyoxyalkylenes according to claim 1 . 4. A surfactant, comprising the interface-active polymer according to claim 3 . 5. The polyoxyalkylene according to claim 1 , where Z E is an organic radical selected from the group consisting of linear or branched, saturated or unsaturated aliphatic hydrocarbyl radicals having 7 to 22 carbon atoms or aromatic hydrocarbyl radicals having 6 to 17 carbon atoms. 6. The polyoxyalkylene according to claim 1 , where —C(═O)—Z is selected from the group consisting of carboxylates of 2-ethylhexanoic acid, isotridecylcarboxylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, isostearic acid, ricinoleic acid, undecylenoic acid and mixtures thereof. 7. The polyoxyalkylene according to claim 1 , where —C(═O)—Z is selected from the group consisting of carboxylates of fatty acid mixtures obtained from palm oil, coconut oil, olive oil, rapeseed oil, soya oil, sunflower oil, safflower oil, linseed oil, peanut oil, castor oil, and tall oil. 8. The polyoxyalkylene according to claim 1 , wherein A has a weight-average molar mass of 15 to 4983 g/mol.
