Laser flash photolysis and time-resolved resonance Raman spectroscopy were applied to elucidate the mechanism of photodegradation of poly(2,6-dimethyl-1,4-phenylene oxide). Based also on the results obtained for several model compounds it is concluded that dissociation of the terminal phenolic...
During processing of poly(ethylene terephthalate) (PET) hydrolytic chain scission, induced by the presence of small amounts of water, is the main cause of degradation. During repeated reprocessing chain scission can also occur because of the presence of other polymeric contaminants like PVC. In...
The pyrolysis pathways of polyethers are described. A method, which is based on these pathways, is proposed for the interpretation of pyrolysis mass spectra of polyethers. The method makes use of pyrolysis data organised in tables, which relate polyether structures with specific masses and mass...
Incorporation of red phosphorous into poly(ethylene terephthalate) (PET) confers good fire retardancy. However, the initial rates and levels of smoke emission of these red phosphorous filled PET samples increase dramatically with increasing loading of phosphous. In order to overcome these...
Thermal degradations of poly(2-(3-phenyl-3-methylcyclobutyl)-2-hydroxyethyl methacrylate) (poly(PHEMA)), poly(2-(3-mesityl-3-methylcyclobutyl)-2-hydro-xyethyl methacrylate) (poly(MHEMA)) and poly(2-(3-tolyl-3-methylcyclobutyl)-2-hydroxyethyl methacrylate) (poly(THEMA)) have been studied using IR...
A dynamic heating experiment was used to examine the influence of temperature on the degradation of the Kraft insulating paper in transformer oil. The degradation was monitored by measuring a number of key indicators on selected samples as a function of progressive ageing. These indicators...
A new polyester polyol was synthesized using 2,4-diethyl-1,5-pentanediol, which has two ethyl groups as side chains. A new polyurethane was synthesized using this polyester polyol. The hydrolysis resistance and the mechanical properties of this polyurethane were investigated. Several kinds of...
The thermal behaviour of two copolymers of poly(vinylidene cyanide-co-methyl α acetoxyacrylate) has been studied by means of dynamic and isothermal thermogravimetric analysis in the range 246–316 °C, and gas chromatography-mass spectrometry. The main volatile product is acetic acid, which...
The translational diffusion coefficient and intrinsic viscosity of poly(1,4-phenylene-1,3,4-oxadiazole) molecules in 96% H 2 SO 4 have been determined at different stages of degradation of the molecules in acid solution at temperature ranging from 82 to 105 °C. The degradation rate constant, k ,...
During stability studies aqueous extractions were carried out on a polyurethane (PU) device. Analysis of the extracts, reconstituted in tetrahydrofuran (THF), gave strong positive results for free monomeric hexane diisocyanate (HDI) when analysed by gas chromatography with mass spectroscopic...
