Polymerization Vinyl Ether

They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers.

Polymerization vinyl ether.

Provided is a method for the polymerization of vinyl ethers catalyzed by complexes of a lithium salt and a polyether. Poly vinyl ether s pves feature a polar ether functionality in each repeat unit are derived from an inex. Shohei ida makoto ouchi mitsuo sawamoto living cationic polymerization of an azide containing vinyl ether toward addressable functionalization of polymers journal of polymer science part a. Living cationic ring opening polymerization.

Polymer chemistry 10 1002 pola 23916 48 6 1449 1455 2010. A general and efficient access toward terminally functionalized poly vinyl ether s. That mediates the facial addition of polar vinyl monomers to an ionic chain end. 58 was quite different from that for the living polymerization.

Macromolecules 2020 53 5 1536 1542. In order to overcome the challenge of direct radical polymerization of vinyl ethers commercial hydroxy functional vinyl ethers such as 2 hydroxyethyl vinyl ether heve were subjected to free radical polymerization generating. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. 124 the fast living cationic polymerization of vinyl ethers with sncl 4 combined with etalcl 2 in the presence of an ester as an added base was reported.

We identified the cationic polymerization of vinyl ethers as a high value target to exemplify such a catalyst controlled approach. The resulting polymers are produced under mild and controlled conditions and are useful in adhesives and coatings as well as in other uses such as for polymer electrolytes in batteries and for viscosity. Poly vinyl ether s with a t g as high as 100 c have been obtained in the living cationic polymerization of vinyl ethers with a bulky tricyclodecane or tricyclodecene unit using hcl zncl 2 in toluene at 30 c. Vinyl ethers ch 2 chor r methyl ethyl isobutyl benzyl are very reactive vinyl monomers.

Vinyl ethers undergo homopolymerization via a cationic mechanism. 125 the cationic. Thienyl chloride initiated living cationic polymerization. On the other hand the stereostructure of living poly 2 benzoyloxyethyl vinyl ether obtained in the absence of added bases meso.

A preferred complex is a complex of lithium tetrafluoroborate and a glyme. This method however is highly sensitive to monomer structure and achieved only 76 m and 64 m in the case of n butyl bve.
