Gelation is promoted by gelling agents. Gelation can occur either by physical linking or by chemical crosslinking. While the physical gels involve physical bonds, chemical gelation involves covalent bonds. The first quantitative theories of chemical gelation were formulated in the 1940s by Flory and Stockmayer. Critical … Visa mer In polymer chemistry, gelation (gel transition) is the formation of a gel from a system with polymers. Branched polymers can form links between the chains, which lead to progressively larger polymers. As the linking continues, … Visa mer It is important to be able to predict the onset of gelation, since it is an irreversible process that dramatically changes the properties of the … Visa mer • Mechanics of gelation Visa mer WebbSome Aspects of the Theory of Gel Formation in Reactions of Polyfunctional Compounds K.A.Andrianov and V.N.Emel'yanov Various theories of gel formation by three … florida institute of technology federal idWebbExamination and comparison of classical and high-technology processing systems using chemical thermodynamics and kinetics; understanding the approaches for chemically synthesizing ceramic material, co-precipitation, sol-gel processing, hydrothermal synthesis, plasma, and CVD.
