Abstract: According to this thesis, Central siloxane cationic polymerization reaction mechanism and response characteristics, to 12 alkyl dimethyl benzyl bromide for cationic emulsifiers, KOH as the catalyst, D4 for the monomer for Central siloxane Cationic polymerization and on the basis of this discussion the Central siloxane cationic emulsion polymerization conditions and factors affecting the course of the proliferation of monomer. The results show that: Mixing speeds and the amount of catalyst are two major factors affecting the conditions, stirring rate sooner, the greater the reaction rate; KOH amount of increase in polymerization rate also increased, then decreased to a certain extent. In addition, when the start of polymerization, Sol beam formed by the latex particles polymerization rate faster monomer concentration of low, single droplet formation of the latex particles polymerization rate slow, high concentrations of monomer and polymerization with the conduct, due to the spread of the role, Concentration of smaller gap between the two, until equilibrium, the two achieve the same concentration.
Key words: Central siloxane; cationic polymerization; dynamic model; dynamics between the proliferation of single transmission
