The process was carried out without any amines with dimethylosulfoxide (DMSO) as interfacial catalyst. It was established that DMSO was between 80–120 mol % to the quantities of applied monomers. Bisphenol A and bisphenol C [2,2-bis(p-hydroxyphenyl),-1,-1 dichloroethylene] were applied as bisphenolic monomers

The aim was to compare the fire hazards (fire growth and smoke toxicity) using different upholstery materials. Four compositions of sofa-bed were compared: three meeting UK Furniture Flammability Regulations (FFR), and one using materials without flame retardants intended for the mainland European market. Two of the UK sofa-beds relied on chemical flame retardants to meet the FFR, the third used natural materials and a technical weave in order to pass the test. Each composition was tested in the bench-scale cone calorimeter (ISO 5660) and burnt as a whole sofa-bed in a sofa configuration in a 3.4 × 2.25 × 2.4 m test room. All of the sofas were ignited with a No. 7 wood crib; the temperatures and yields of toxic products are reported. The sofa-beds containing flame retardants burnt somewhat more...
