Following these previous results, we investigated in this study the influence of the polymerization conditions(monomer concentration and polymerization temperature) on the structure of poly(divinyl formal). [Pg.74]

In conclusion, the structure of poly(divinyl formal) was shown to vary with the polymerization conditions (Table I). It is expected that highly stereoregular polymers are obtainable by selecting proper polymerization comditlons. These results will be described elsewhere, together with the kinetic analysis of the cyclopolymerization process. [Pg.79]

The relation between the tendency to form rings and the constitution of the monomer is not yet fully understood. However, the high ratios of k lkc for methacrylic anhydride and divinyl formal are striking (Table 16-2). [Pg.543]

The related monomers divinyl formal (30a), acetal (30b), and dimethylketal (30c) also undergo facile free-radical polymerization to give mainly soluble polymers [140-145],... [Pg.180]
