Investigations of Curing Chemistry and Hydrolytic Stability of Polyimide - on - Metal Interfaces
MRS Proceedings, 1993AbstractPolyimide-on-metal interfaces relevant to electronics packaging applications have been studied by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Two polyimides with different backbone structures were considered: (i) biphenyltetracarboxylic dianhydride (BPDA) - p-phenylene diamine (PDA) and (ii) 4,4 ...

Effect of Cement Chemistry on Accelerated Curing Cycle of Concrete
PCI Journal, 1984This paper presents the results of an investigation into improving the high early compressive strength of concrete containing Type III cement in a prestressed concrete manufacturing plant using accelerated curing techniques. The effects of physical and chemical cement characteristics are discussed with emphasis on C 3S and C3A contents, SO3 ...

Journal of Agricultural and Food Chemistry, 1992
The chemistry, aroma, solubilities (herane and 95% ethanol), and smoking quality of cured tobacco from three typical flue-cured varieties that produce glandular trichomes on the surface of the green leaf and an atypical aglandular breeding line were compared. The glandular tobaccos produced more characteristic tobacco aroma than the aglandular tobacco.

Investigations on the cure chemistry and polymer properties of benzoxazine–cyanate ester blends
European Polymer Journal, 2009Abstract Thermosetting polymer blends composed of bisphenol A based benzoxazine (BA-a) and cyanate ester (BACY) were prepared via co-curing of benzoxazine with cyanate ester. DSC results manifested a multiple curing pattern with associated heat of reaction implying a co-reaction between oxazine moiety and cyanate group.

Surface chemistry of carbon black through curing process of epoxy resin
Carbon, 1995The effects of oxidized carbon black surfaces on the epoxy resin curing process were examined by differential scanning calorimetry (DSC). The addition of oxidized carbon black accelerated the initial cure reaction of the epoxy-amine system. Peak temperature in DSC exotherm of the resin system falls in proportion to the ratio of surface ester groups on ...

Decomposition of peroxides by transition metal ions in anaerobic adhesive cure chemistry
International Journal of Adhesion and Adhesives, 1999Anaerobic adhesives are single component acrylic adhesives which remain stable for long periods of time but polymerize rapidly when confined between two closely fitting metallic surfaces. Transition metal ions on the substrate surface play a key role in catalysing the decomposition of cure initiators to generate free radicals. Readily reducible organic

Flavor and Chemistry of Uncured and Cured Meat of Harp Seal (Phoca Groenlendica)
1999Flavor is an important sensory attribute of foods in general and of muscle foods in particular. While the nutritional aspects of food are important upon consumption, flavor and color are among the primary factors influencing the customers even prior to consumption. Flavor of foods is influenced by both taste and aroma-active components (Shahidi, 1989).

Cleavable Thermosetting Epoxies: a Tool for Monitoring Cure Chemistry Perturbation at an Interface
MRS Proceedings, 1993AbstractA diepoxide containing a disulfide linkage, capable of being reductively cleaved was synthesized. This compound was cured with standard amine curing agents to form intractable network polymers, which were then decomposed into soluble fragments, allowing the effects of network formation on cure chemistry to be evaluated.
