摘要:
The invention relates to the production and use of polyester polyols, formed from at least one carboxylic acid hydride and ethylene glycol, wherein a specialized reaction control stustantially suppresses the formation of 1,4-dioxane from diethylene glycol.
摘要:
Polyester polyols are produced from at least one carboxylic acid hydride and diethylene glycol by a process in which the formation of 1,4-dioxane is suppressed. These polyester polyols are useful for producing polyurethane (PUR) and polyisocyanurate (PIR) foams and metal composite elements containing these PUR or PIR foams.
摘要:
The present invention relates to polymer dispersions in polyester polyols, a process for producing them and their use for the production of polyurethanes, in particular microcellular polyurethanes. These polyester polyols have sulfur atoms and are free of olefinically unsaturated groups.
