OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...

The authors are aware that virtually every government laboratory and agency is grappling with the problem of technology transfer to American industry. This activity is in response to the Federal Technology Transfer Acts (FTTA) of 1986 and 1989, which were conceived in an attempt to make American industry more competitive world wide. These acts in turn are a response to the fact that so many Ame...

We have developed a dynamic self-consistent field theory, without any adjustable parameters, for unentangled polymer blends under shear. Our model accounts for the interaction between polymers, and enables one to compute the evolution of the local rheology, microstructure, and the conformations of the polymer chains under shear self-consistently. We use this model to study the interfacial dynam...

Dense CO2 can be used as an environmentally-benign polymer processing medium because of its liquid-like densities and gas-like mass transfer properties.In this work, polymer bio-blends of polycarbonate (PC), a biocompatible polymer, and polycaprolactone (PCL), a biodegradable polymer were prepared. Dense CO2 was used as a reaction medium for the melt-phase PC polymerization in the presence of d...

to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...

The use of blends of electron and hole transporting polymers has been shown to increase exciton dissociation and efficiency in polymer-based photovoltaics. We compare plain M3EHPPV devices to M3EH-PPV:CN-ether-PPV blend devices, demonstrating the improved performance of blends. We vary the polymer layer thickness and device electrodes for M3EHPPV:CN-ether-PPV polymer blend devices to investigat...

The phenomenon of coarsening has been the topic of intensive study, chiefly in material science, where droplets coalesce1,2 or successive layers of material deposited on a substrate form complex morpholgies3,4. These problems are of technological interest because properties of composite materials such as polymer blends and alloys depend on the size and structure of included droplets5,6; likewis...
