Designing Polymerization Reaction Systems | AIChE

Polymerization reactors are rarely built to make only one product over the entire life of the equipment. Normally, a reactor switches among a handful of products. In addition, markets change, so manufacturers prefer a flexible design — one that is good today, and, with little or no modification, 30 years from now. Reactor configuration.

Polymerization in emulsion microdroplet reactors - NASA/ADS

The goal of this research project is to utilize emulsion droplets as chemical reactors for execution of complex polymerization chemistries to develop unique and functional particle materials. Emulsions are dispersions of immiscible fluids where one fluid usually exists in the form of drops. Not surprisingly, if a liquid-to-solid chemical reaction proceeds to completion within these drops, the .
