چکیده
Distributed Multimedia Information System Laboratory School of Computer Science, Florida International University Miami, FL 33199, USA Abstract Styrene Monomer (SM) has been widely used for producing polystyrene (PS), acrylonitrile-butadiene-styrene (ABS) and styrene-acryonitrile (SAN) in the petrochemical industry. From 1994 to 2001, several serious accidents occurred in Taiwan due to styrene monomer’s inherent instability, deviation of operation and others. In this research, thermal polymerization under low temperature is characterized by an isothermal microcalorimeter, thermal activity monitor (TAM). Thermograms show that an autocatalytic reaction occurs in the temperature range from 50°C to 80°C. In addition, the exothermic kinetics is also investigated. Such weakly exothermic phenomena could not be detected by traditional calorimeters such as differential scanning calorimeters (DSC) and vent sizing package (VSP) because of

Synthesis, Characterization and Thermal Stability Study of Styrene-based Ionomers I) Programmed Heating Experiments (10 oC/min to 500 oC)
Ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. The objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. These materials have been synthesized by neutralization of the respective copoly...
متن کاملThe Effect of Microwave on Migration of Styrene Monomer Polystyrene Food Packaging and Compared to other Thermal Processes
The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...
متن کاملEffect of carbon black and fly ash co-fillers content on mechanical and thermal behaviors of styrene butadiene rubber compounds
Fly ash (FA) is produced as a waste byproduct during the burning process of coal in thermal power plants whose cost is primarily associated to cleaning and transportation. It possesses mechanical properties on account of its constituents like silica and alumina. The use of FA as filler in styrene butadiene rubber (SBR) was of researchers’ interest to reinforce and/or to reduce product cost. In ...

This study aimed to extend the shelf life of walnut kernels by appropriate packaging conditions and physical methods. For this purpose, the kernels were heated at 50 or 70°C for 2 or 10 minutes. About 100g of walnuts were packed in low-density polyethylene (LDPE) packages under ordinary, vacuum or nitrogen conditions. Samples were stored for 18 months at room temperature. Peroxide value and aci...
