Publication number: 20110257284Abstract: The present invention describes a process for producing flame-retardant polyurethane foams. The process of the invention includes the use of hyperbranched, nitrogen-containing polymers for providing flame retardancy to polyurethane foams. The amounts used of the hyperbranched compounds are preferably from 5 to 20% by weight, based on the polyol component. The N content of preferred nitrogen-containing compounds is at least 2% by weight. The N content of the polyurethane foams of the invention is from 1 to 8% by weight from the hyperbranched polymer. Compounds in particular used are hyper-branched polyureas, hyperbranched polyamides, and in particular hyperbranched polylysines, hyperbranched polyisocyanurates, and hyperbranched polyesteramides. An advantage of the use of the compounds of the invention is that the polyurethane foams can be rendered flame-retardant without the use of, or by using markedly reduced amounts of, halogen-containing flame retardants.Type: ApplicationFiled: April 12, 2011Publication date: October 20, 2011Applicant: BASF SEInventors: Bernd BRUCHMANN, Daniel SCHONFELDER, Jens FERBITZ, Andrea EISENHARDT, Maxim PERETOLCHIN
