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.

Vinyl ether monomers.

These plastics are noted for their transparency resistance to breakage and elasticity. With an ever expanding product portfolio basf can satisfy your needs for functional vinyl monomers now and in the future. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.

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. Acrylate polymers are a group of polymers prepared from acrylate monomers. They are also commonly known as acrylics or polyacrylates acrylate polymer is commonly used in cosmetics such as nail polish as an adhesive. I of laboratory interest only.

However radical curable monomers have disadvantages such as 1 inhibition of polymerization by oxygen 2 the large volume shrinkage. An industrially important example is vinyl chloride precursor to pvc a plastic. Ii affording vinyl ethers as side products. 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.

Advanced green syntheses of vinyl ether monomers. 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. Basf s global leadership in acetylene chemistry has made it the leader for development and production of functional vinyl monomers.

Iv potentially upgradable for reasonable production of vinyl ether monomers. Vinyl ethers undergo homopolymerization via a cationic mechanism. Reactions that lead to vinyl ethers can be divided into four groups. Cyclohexyl vinyl ether chve 2182 55 0.

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Iso butyl vinyl ether ibve 109 53 5. Iii used in industry to produce vinyl ether monomers.
