Vinyl Ether Monomers

However radical curable monomers have disadvantages such as 1 inhibition of polymerization by oxygen 2 the large volume shrinkage.

Vinyl ether monomers.

Iso butyl vinyl ether ibve 109 53 5. With an ever expanding product portfolio basf can satisfy your needs for functional vinyl monomers now and in the future. Acrylate polymers are a group of polymers prepared from acrylate monomers. Cyclohexyl vinyl ether chve 2182 55 0.

Conventional web curable monomers are classified in radical curable monomers such as meth acrylates vinyl compounds and in cationic curable monomers such as vinylether epoxy and cycloaliphatic compounds. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. The polymers formed have a ketone end group e g 19 scheme 9 functionality can be introduced on z or r to modify reactivity or to tailor the end groups as in the examples 20 22. They are also commonly known as acrylics or polyacrylates acrylate polymer is commonly used in cosmetics such as nail polish as an adhesive.

These plastics are noted for their transparency resistance to breakage and elasticity. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. Vinyl ethers undergo homopolymerization via a cationic mechanism. Ii affording vinyl ethers as side products.

Basf s global leadership in acetylene chemistry has made it the leader for development and production of functional vinyl monomers. An industrially important example is vinyl chloride precursor to pvc a plastic. Our offer comprises additional technical support ranging from analytical services to joint r d activities to help you become more successful with our products. In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom.

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Advanced green syntheses of vinyl ether monomers. The results of polymerization and initiation experiments at 25 c show that the alternating copolymerization of maleic anhydride monomer 1 and ethyl vinyl ether monomer 2 is consistent with a. 21 the vinyl ether transfer agents like other vinyl ethers generally show marked acid sensitivity and are not suited for use with acidic monomers e g acrylic acid aa methacrylic acid maa.

I of laboratory interest only. Previous approaches toward stereoselective vinyl ether polymerizations have exclusively relied on chain end control to dictate facial addition to the propagating oxocarbenium ion which has provided access to isotactic pves in specific cases but is not general to alkyl vinyl ether monomers as a class 13 19. Basf combines 90 years of experience in the development of high quality functional vinyl monomers including vinyl ethers and n vinyl compounds with state of the art know how and technology.
