Application of Genetic Algorithm to Determine Kinetic Parameters of Free Radical Polymerization of Vinyl Acetate by Multi-objective Optimization Technique

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...

Compression, supramolecular organization and free radical polymerization of ethylene gas

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...

The Mechanism of Stereoregulation in Free-Radical Polymerization of Bulky Methacrylates

Theoretical calculations are performed to explore the origin of inherent tacticity in bulky methacrylates. Geometries and conformer distributions of monomers and oligomeric propagating radicals are calculated to study the impact of steric bulk and π-stacking interactions on the preferences for meso versus isotactic propagation. Consistent with the previous qualitative analyses by Satoh and Kami...

Synthesis and Characterization of Optically Active Helical Vinyl Polymers via Free Radical Polymerization

A facile synthetic route to prepare the dual-functional molecule, 2,5bis(40-carboxyphenyl)styrene, was developed. The esterification of this compound with chiral alcohols, that is, (S)-(þ)-sec-butanol/(R)-( )-sec-butanol, (S)-(þ)-secoctanol/(R)-( )-sec-octanol, and D-(þ)-menthol/L-( )-menthol, respectively, yielded three enantiomeric pairs of novel vinyl monomers, which underwent radical polyme...
