Vinyl Ether Monomers Chempoint

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 ether monomers chempoint.

With an ever expanding product portfolio basf can satisfy your needs for functional vinyl monomers now and in the future. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Our offer comprises additional technical support ranging from analytical services to joint r d activities to help you become more successful with our products. Vinyl ethers undergo homopolymerization via a cationic mechanism.

However radical curable monomers have disadvantages such as 1 inhibition of polymerization by oxygen 2 the large volume shrinkage. Vinyl ether monomers can be used with acrylate oligomers to afford hybrid curable systems 13 which combine the advantages of both vinyl ether chemistry and acrylate based technology. Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan. Well optimized catalysts produce vast quantities of isotactic polypropylene in which the side chains all face the same way.

Teator and leibfarth report a general protocol to polymerize a variety of such vinyl ethers isotactically see the perspective by foster and o reilly. Add an oxygen into the monomer though and that degree of uniformity becomes harder to enforce. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. The main manufacturer of vinyl ether monomers and resins is basf.

Basf s global leadership in acetylene chemistry has made it the leader for development and production of functional vinyl monomers. 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. 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. Poly vinyl ethers and their copolymers find many applications such as adhesives release and surface coatings lubricants greases elastomers anticorrosion agents molding.

They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Excellent properties choice of a wide range. An industrially important example is vinyl chloride precursor to pvc a plastic.
