Thiol Vinyl Ether

Interestingly the relative number of thiol functional group moles converted and the total.

Thiol vinyl ether.

Poly methyl vinyl ether solution. These thiol ene polymerizations are photoinitiated without the use of photoinitiator molecules. Vinyl ether functionalized cyclic phosphotriester monomer 2 ethylene glycol vinyl ether 1 3 2 dioxaphospholane 2 oxide evep 1 was synthesized by following a typical condensation method. The advantages of the vinyl ether functionality is its capability to form stable or alternatively dynamic covalent bonds.

The kinetics of the vinyl and upe group reactions are mirrored by the thiol conversion in figure 12 a which exhibits a very rapid initial loss of thiol groups reaction with vinyl ether followed by a much slower conversion reaction with upe. P toluenesulfonic acid ptsa induced a cationic thiol ene reaction to generate a thioacetal in high yield whereas 2 2 azobisisobutyronitrile resulted in a radical thiol ene reaction to give a thioether also in high yield. Thiol ene free radical and vinyl ether cationic hybrid photopolymerization macromolecules. Coupling of ethylene glycol vinyl ether eve to 2 chloro 3 oxo 1 3 2 dioxaphospholane cop in the presence of triethylamine tea in dichloromethane dcm.

A thiol monomer is shown to copolymerize with vinyl ether allyl acrylate methacrylate and vinylbenzene monomers. Structure and properties of ethers the geometry around the o atom of an ether ror is similar to that. Ethyl isobutyl ether allyl vinyl ether. Product name linear formula.

Methoxy peg thiol methoxypolyethylene glycol thiol. 1 product result match criteria. Thiols r s h thiols r s h and sulfides r s r are sulfur analogs of alcohols and ethers respectively sulfur replaces oxygen. C 3 h 6 o n.

This reaction was first reported in 1905 but it gained prominence in the late 1990s and early 2000s for its feasibility and wide range of applications. The sequential thiol vinyl ether copolymerization and the vinyl ether cationic polymerization result in cross linked networks with thermal and mechanical properties that are combinations of each system.
