1,3,5-Trioxanes 726 (Z = O) are trimers of aldehydes or ketones formed by acid-catalyzed condensations of the monomers. 1,3,5-Trithiane 726 (Z = S) is prepared by passing H 2 S through formaldehyde and hydrochloric acid <1943OSC (2)610>.
1,3,5-Trioxane, sometimes also called trioxane or trioxin, is a chemical compound with molecular formula C 3 H 6 O 3. It is a white, highly water-soluble solid with a chloroform -like odor.
1 sty 2013 · Polymers can be synthesized by polymerizing monomers with ring structure as shown in Table 11.1. The polymerization of these compounds has some aspects of both chain and step polymerizations as far as kinetics and mechanisms are concerned.
Polyoxymethylenes having a degree of polymerization up to P 1"'-..J 100 are undoubtedly linear; their thermal and chemical stability depends on the nature of the end groups. POM diols are unstable, POM diacetates are thermally stable, PO.l\1 dimethyl ethers are, in addition, stable to alkali.
Linear polymers are macromolecules of many repeating units called monomers arranged in a straight line. A linear polymer can have side groups attached to the backbone. These side groups can be substituted with drugs, targeting moieties, solubilizers, and any other active ingredient needed for targeted and controlled drug delivery [158].
TRIOXANE, the cyclic trimer of formaldehyde, is a comparatively little-known chemical compound possessing unique physical and chemical characteristics. It should not be confused with, the so-called commercial trioxymethylene which is really paraformaldehyde.
Linear polymers are long-chain molecules formed by the repetitive linking of monomer units in a straight, unbranched manner. This structure contributes to their unique properties and classifications, influencing how they are named and categorized based on their origins and structural characteristics.
