nature : manufacturing polymer one of the ways. Will solvent-soluble monomer addition polymerization initiator for reaction. In general solvent return temperatures, can be effective in controlling the reaction temperature, but can also use the solvent evaporation Pai heat to dissipate into the atmosphere by the reaction released heat. If the production of polymer can be dissolved in solvents, is the product solution, dumped into some empirical polymer liquid polymer that precipitation can be distilled to remove the solvent solution in polymer. Low molecular weight, poor uniformity, such as vinyl acetate which polymerization in ethyl acetate. If the polymer in the solvent empirical, with the reaction of the polymer for generating continuous precipitates out, also known as polymerization precipitation polymerization (precipitation polymerization). High molecular weight, uniformity are better, such as vinyl chloride polymerization in methanol. Solution polymerization only suitable for the manufacture of low molecular weight polymer, the polymer solution can be directly used for coating.
