preparation example Construction

[0052] One suitable preparation technique is described in US Patent 4,616,074, the disclosure of which is incorporated herein by reference. In the method disclosed in US Pat. No. 4,616,074, polymerization is carried out in a continuous, semi-continuous or batch manner, and the polymerization reaction is initiated at 40°C to 90°C. Use thermal decomposition initiators such as ammonium persulfate or potassium persulfate, or at lower temperatures redox initiators such as tert-butyl hydroperoxide / bisulfite. Emulsifiers are typically included in the reaction medium at a concentration of from about 1% to about 3% by weight, based on the total weight of the monomer feed, in order to maintain a stable aqueous dispersion. Suitable emulsifiers include, but are not limited to, sodium lauryl sulfate, sodium dodecylbenzenesulfonate, and other ammonium and alkali metal alkylarylsulfonates and alkyl sulfates. Polymerization is carried out at a pH below about 5.0 to maintain the insolubility ...
