Photodegradation of incombustible polymer materials [high-density (HD) and low-density (LD) polyethylene (PE) containing 0.5 to 2.0 phr of decabromodiphenyl ether (DBDE) or tetrabromobisphenol A (TBA) as a flame retardant] were studied using an Okazaki Large Spectrograph (OLS). Samples were irradiat

Several thermal degradative methods were employed for elucidation of structures of two furfuraldehyde insoluble and infusible resins. A combination of pyrolysis at reduced pressure, (direct-inlet pyrolysis)-(mass spectrometry) and flash-pyrolysis in GC/MS and GC/FT-i.r. systems led to the identifica
Pulsed electric discharge (PED) and bioremediation were combined to create a novel two-stage system which dechlorinates the halogenated pollutants, 2,4dichlorophenol and perchloroethylene, with repetitive (0.1-1 kHz), short pulse (βΌ100 ns), low voltage (40-80 kV) discharges and then mineralizes the
## Abstract A special model system based on a diglycidylester (1) and 4,4β²βdiaminodiphenylmethane (2) was used to characterize the network structure of epoxy resins. Networks with cure degrees of 0,72 to 0,82 were prepared. These networks could be cleaved by hydrolysis after curing, and the network
