Procedure

Four different polymer particles were prepared containing different proportions of monomers in the shell as shown in Table 7. Each preparation began with 50 mL of latex from Example 6A and 1 g of a mixture of chloromethylstyrene and 2-vinylnaphthalene in the appropriate ratio to produce 10, 30, 70, and 100 percent (w/w) chloromethylstyrene/2-vinylnaphthalene shells (lots 6.1, 6.2, 6.3, and 6.4, respectively, the latex from Example 6A having been designated as 6.0). For each preparation, 50 mg of potassium persulfate was used in one-hour polymerizations at 95°-100° C. The monomer conversions and optical densities at 340 nm of a 1:100 dilution in water of the polymer particle latices are also shown in Table 7; the solids content was 14%
