Predictive Control of Average Composition and Molecular Weight Distributions in Semibatch Free Radical Copolymerization Reactions
Control of copolymer composition and molecular weight distributions is important, since they partially govern material performance. This work uses a simple but robust approach to approximate predictive control of average composition and molecular weight during free radical copolymerization, based on detailed kinetics obtained by ACOMP (automatic continuous online monitoring of polymerization re...
متن کاملEvolution of composition, molar mass, and conductivity during the free radical copolymerization of polyelectrolytes.
Despite their importance in biological and technological contexts, copolymeric polyelectrolytes (or "copolyelectrolytes") continue to present challenges to theorists and experimentalists. The first results of a unified approach to the kinetics and mechanisms of copolyelectrolyte synthesis and the physical characteristics of the resulting polymers are presented. The free radical copolymerization...
متن کاملModels for on-line control of batch polymerization processes State and parameter estimation for semi-batch free-radical emulsion copolymerization processes
This report presents work done as part of the compulsory specialization project in the final year of the study program for the degree of M.Sc. in Chemical Engineering at the Norwegian University of Science and Technology. The project work has been carried out in close collaboration with Cybernetica AS, who proposed the project. The project serves as an extension to a summer internship with Cybe...
متن کاملDenture base polymers, poly methyl methacrylate improved using free radical copolymerization
Poly methyl methacrylate (PMMA) is the most common material used in Prosthodontics. Several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes cross linking or copolymerization. The innovative method for improving the physical properti...
متن کاملExperimental observation of crossover from noncondensed to counterion condensed regimes during free radical polyelectrolyte copolymerization under high-composition drift conditions.
By combining detailed online kinetics of comonomer consumption with light scattering, viscosity, and conductivity data, experimental detection of changing degrees of counterion condensation was achieved by using comonomers of widely separated reactivity ratios that produced large composition drifts during synthesis. Endproducts of such syntheses contained mixtures of chains of widely varying li...
