The present invention relates to sulfur-containing polyester polyols and to the preparation and use thereof.

Sulphur-containing polyester polyols, their production and use

The present invention relates to a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition, a chain extender, and a polyol composition, wherein the polyol composition comprises a polyol (P1) which has a molecular weight Mw in the range from 1500 to 2500 g/mol and has at least one aromatic polyester block (B1). The present invention further relates to a process for producing a shaped body comprising such a thermoplastic polyurethane, and to shaped bodies obtainable or obtained by a process of the invention.

Polyurethane with improved tear strength

The invention relates to a process for mineral oil production, in which an aqueous saline surfactant formulation comprising a surfactant mixture of at least one anionic surfactant of the general formula R&#x2014;O&#x2014;(CHC(CH)HO)&#x2014;(CHCHO)&#x2014;SOM and at least one anionic surfactant of the general formula R&#x2014;O&#x2014;(CHCHO)&#x2014;SOM and a base is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to the surfactant mixture, a concentrate comprising the surfactant mixture and a manufacturing process as well as the use of the surfactant mixture and the con- centrate in the production of mineral oil from underground mineral oil deposits.

Robust alkyl ether sulfate mixture for enhanced oil recovery

The present invention relates to a method for producing a molded body (MB) comprising the production of a thermoplastic polyurethane, the production of a molded body (MB*) from the thermoplastic polyurethane, heating the molded body (MB*) to a temperature below the temperature at which there is permanent deformability of the molded body (MB*), and above the switching temperature of the thermoplastic polyurethanes, elongating the heated molded body (MB*) with obtention of a molded body (MB), and cooling the molded body (MB) to a temperature below the switching temperature of the thermoplastic polyurethane, and the molded body obtained or obtainable by such a method. The present invention further relates to a thermoplastic polyurethane with shape memory and the use of a thermoplastic polyurethane for producing a molded body with shape memory effect in a temperature range from 0&#xb0; C. to 130&#xb0; C.

TPU shrink material

Radiation-curable, polyester acrylate-containing compositions (I) obtainable by reacting 0.5 to 20 mol % of a polyester polyol (A) and 0.5 to 30 mol % of a polyester diol (B) with 1 to 10 mol % of phthalic anhydride (C) and 65 to 75 mol % of (meth)acrylic acid (D) in the presence of an acidic esterification catalyst, a hydrocarbon (L), and a polymerization inhibitor. Reaction temperatures range from 60 to 140&#xb0; C. The hydrocarbon (L) functions as solvent, forms an azeotropic mixture with water, and is removed distillatively after esterification. Water formed in the reaction is removed azeotropically. After neutralization of the esterification catalyst, free (meth)acrylic acid is reacted with an epoxide compound (E) in an amount equivalent to the acid number of the reaction mixture. The compound (E) has at least two epoxide groups per molecule. The compositions are suitable for coating the surfaces of solid substrates.
