Abstract:
The present invention relates to a method for producing thermosetting resin moldings, to the thermosetting resin moldings as such, to the use of the thermosetting resin moldings as structural components and to the use of a thermoplastic polymer having a porosity in the range of from 10 to 90% to increase the toughness of a thermosetting resin.
Abstract:
The invention relates to a method for producing a polyester polyol comprising the following method steps: (a) producing a reaction mixture comprising the following components: A: at least one carboxylic acid obtained from natural raw materials, having at least two acid groups, B: at least one multivalent alcohol, C: at least one organic phosphite compound, D: at least one Lewis acid; (b) heating the reaction mixture to a temperature of at least 160°C and separating the water that is generated during the reaction; (c) heating the reaction mixture to a temperature of at least 210°C at a pressure below 1013 mbar for a period of 0.1 to 25 hours.
