Abstract
2-Methacryloyloxyethyltrimethylammonium chloride (MMAC) was polymerized in the presence of poly(sodium acrylate) as the template polymer and potassium persulfate as the initiator in water. The polymerization was accompanied by the precipitation of complex of poly(MMAC) and poly(sodium acrylate). A negative template effect (polymerization rate reduction) was observed when the template of low degree of polymerization (Pn) was used, while increase of Pn of the template decreased such negative effect. Coexistence of the template and sodium chloride to increase ionic strength of the reaction medium showed great negative template effect even by using the template of high Pn. The results were interpreted based on zip and pick-up mechanisms. The polymerization of MMAC took place thermally in the presence of the template of high Pn, indicating the effect of organization of the monomer.
