Abstract Polyethylene terephthalate (PET #1) and polyolefin plastics such polyethylene (HDPE #2, LDPE #4) and polypropylene (PP #5) are major products from the chemical industry, and they comprise a significant fraction of municipal solid waste that ends up in landfills or as litter and marine debris. The reuse of these polymeric materials can be optimized through systems analysis with a view on materials flow analysis, techno-economics, environmental life cycle assessment, and consequential soc...

The free-radical retrograde-precipitation (FRRPP) process was recently brought into the quantitative areas of work, based on the discovery of possibility of flat temperature profiles in spherical reactive domain systems. With an approximate decoupling analysis of the energy equation from the component-balance equations, these flat temperature profiles were found to be either stable or unstable. Moreover, resulting evolution of the flat profiles has been found to be expressed analytically through...

In this paper, carbon dioxide (CO2) is used to form a high-density microcellular thermoplastic foam structure in order to reduce polymer consumption and facilitate dispersion of Mg (OH)2 and nanoclay fillers. A twin-screw extruder system was used to predistribute inorganic fillers into the ABS polymer, resulting in composite ABS/filler pellets. This is followed by the use of a single-screw extruder wherein supercritical carbon dioxide is introduced into the formulation. Finally, the resulting fo...

In this article, supercritical carbon dioxide (scCO2) is used to form a high density microcellular foam structure to reduce the polymer use and facilitate dispersion of Mg(OH)2 and Nanoclay fillers. A twin-screw extruder system was used to predistribute the inorganic filler from the PP polymer, resulting composite PP/filler pellets. This followed by the use of a single-screw extruder wherein supercritical carbon dioxide is introduced in the formulation. Finally the resulting foam PP/filler/CO2 p...

Ruthenium trichloride (RuCl3 or RuIII) catalyzed polymerization of methylmethacrylate (MMA) initiated with n-butylamine (BA) in the presence of carbon tetrachloride (CCl4) by a charge-transfer mechanism has been investigated in a dimethylsulfoxide (DMSO) medium by employing a dilatometric technique at 60°C. The rate of polymerization (Rp) has been obtained under the conditions [CCl4]/[BA] ⩽ 1 and [CCl4]/[BA] ⩾ 1. The kinetic data indicate the possible participation of the charge-transfer complex...

It was shown in Chap. 3 that a polymerization system can start as a conventional precipitation system and end as an FRRPP system, especially if the phase diagram exhibits an hourglass-shaped phase envelope at relatively high polymer molecular weight. This sets up the arguments for other types of shifts from UCST- and LCST-based chain polymerizations, especially in cases wherein multiple monomers are involved. The analysis here will be made for two monomers (copolymerizations), but can be easily ...

An attempt was made to determine the existence of LCST behavior for the PMMA–MMA–n-Pentane binary system at a reasonable temperature. For the cloudpoint studies, primary standard PMMA (HI < 1.1) was purchased from Pressure Chemical Corp. (Pittsburgh, PA), with a molecular weight of 6,500 g/mol. As-received MMA was used in the determination of cloudpoint. The same apparatus was used in this study, as the one used for cloudpoint experiments in Sect. 1.1 of Caneba (2010). A constant proportion of P...

Even in neutralized form, VA–AA-copolymers and their emulsions in water can undergo various modification reactions, either catalyzed by acids or bases. These modification reactions have been carried out either to probe the reaction mechanism, to generate a desired product, and/or as a condition for an application that could use the VA–AA-based emulsion copolymers.
