Novel polyacetal terpolymers of trioxane and alpha, alpha-and alpha, beta-isomers of glycerol formal and functional derivatives thereof

摘要

Cationic polymerization of trioxane and a mixture of α,α- and α,β-isomers of glycerol formal (or their ester derivatives) yields acetal terpolymers having pendant functional groups (i.e., hydroxyl or ester groups pendent from the polymer's backbone). The glycerol formal monomers employed in this invention may include functional groups selected from hydroxyl or ester moieties which are protected from, and thus survive, the polymerization process with trioxane. These groups may then be present as functional reactive sites for the subsequent synthesis of block polymers and/or to chemically bind modifiers to the acetal terpolymer backbone, for example.
