Polymeric particles with affinity for 4-dimethylaminipyridine (DMAP) were developed by molecular imprinting using supercritical carbon dioxide (scCO2) technology, cleanup of this potentially genotoxic impurity from crude mixtures Active Pharmaceutical Ingredients (APIs). DMAP-molecularly imprinted polymer (DMAP-MIP) and the respective control, non-molecularly (NIP) produced free radical polymer...

Emulsion polymerization is one of the most important and versatile polymerization processes. About 10 million tonnes of polymer latices are produced annually for a variety of applications, such as coatings and paints. A key step in most applications is film formation upon evaporation of the dispersing medium, rendering aqueous dispersions particularly environmentally benign. Polymer dispersions...

Of all polymerization methods, catalytic polymerization offers the broadest scope of microstructure control. Stereoregularity, comonomer incorporation and sequences, molecular weights, and molecular weight distributions can be controlled by the catalyst structure. Polyolefins are produced on a vast scale of nearly 100 million tons annually, predominantly by catalytic polymerization. High-densit...

A Multi-objective optimization procedure has been developed to determine some kinetic parameters of free radical polymerization of vinyl acetate based on genetic algorithm. For this purpose, mathematical modeling of free radical polymerization of vinyl acetate is carried out first and then selected kinetic parameters are optimized by minimizing objective functions defined from comparing exp...
