| titleOfInvention | Method of producing polyether-ester polyols and use thereof to produce hard or foamed polyurethane materials |
| abstract | FIELD: chemistry.SUBSTANCE: present invention relates to a method of producing polyether-ester polyols, wherein starting compounds with Zerewitinow-active hydrogen atoms (a) react with at least one alkylene oxide (b) in the presence of at least one amine (c), selected from a group consisting of a tertiary amine, unsubstituted imidazole and substituted imidazole, in the presence of at least one fatty acid ester (d) and where 99 wt % of the starting compounds with Zerewitinow-active hydrogen atoms (a) are embedded in the obtained polyether-ester polyol, wherein component (d) is added before, during or after dosing component (b), and before dosing component (b) the polyether-ester polyol (e) in amount of 3.0-20.0 wt % with respect to all components (a), (b), (c), (d) and (e) is mixed with components (a), c and optionally (d). The invention also describes a polyether-ester polyol obtained using said method, use thereof to make foamed polyurethane material and the foamed polyurethane material.EFFECT: creating a method of producing polyether-ester polyols which enables to completely embed fatty acid esters into the formed polyether-ester polyols, which in turn improves holding capacity of foam material compositions for hydrocarbon-based foaming agents, thereby enabling fast production of flexible solid foam.15 cl, 4 dwg, 4 tbl, 10 ex |
