Synteza i właściwości poliuretanów otrzymanych z glikolizatów uzyskiwanych z odpadowej pianki polieterouretanowej

摘要: - The course of waste polyurethane foam glycolysis with 1,4-butylene glycol (BDO) or polyoxyethylene (PEG 300), dependently on PUR foam:glycol weight ratio and the kind agent, was investigated (Table 1, Fig. 1 2). Urethane prepolymer obtained from 4,4'--methylene-diphenyldiizocyanate (MDI) oligo(ethylene-butylene adipate) (,,Poles 55/20") then extended either mixture product BDO PEG 300 itself following properties were measured: storage modulus (E'), tensile hardness, type used (Fig. 3-6). It found that use products in syntheses improved their thermo-mechanical strength (expressed £ ' value) at temperature below zero as well tension set break hardness.
