Sym-Trioxane

All of these polymers are linear with the exception of sym-trioxane [frtrioxymethylene) (HCHO)3] and tetraoxymelhylene HCHO)4, both of which are true polyoxymethylenes, although they are not prepd by the polymerization of monomeric formaldehyde... [Pg.546]

The closely related monomer, sym-trioxan, is a crystalline trimer of formaldehyde, and again polymerizable by cationic means [151, 160]. However, considerable induction periods are observed in its solution polymerization, and the interpretation of kinetic data is additionally complicated by the formation of equilibrium amounts of monomeric formaldehyde as well as polyoxymethylene.

Although formalin can be employed, the submitters find the recommended procedure to give a better quality of elemental silver. Pure a-trioxy methylene (sym-trioxane) is not suitable. [Pg.19]

Trioxane n (sym-trioxane, triformol, trioxin) CH2OCH2OCH2O. The stable, cyclic trimer of formaldehyde, a colorless, crystalline solid. It is easily depolymerized in the presence of acids to its monomer, or may be further polymerized to form acetal... [Pg.1008]

An example of the importance of end-group control is in acetal resin or polyoxymethylene (POM). As normally prepared from cationic polymerization of sym-trioxane, this polymer has —OH end groups, which readily initiate depropagation to formaldehyde (2) by a molecular mechanism (9) ... [Pg.2101]
