Vinyl ether monomers chempoint.
An industrially important example is vinyl chloride precursor to pvc a plastic.
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.
Excellent properties choice of a wide range.
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 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.
However radical curable monomers have disadvantages such as 1 inhibition of polymerization by oxygen 2 the large volume shrinkage.
Well optimized catalysts produce vast quantities of isotactic polypropylene in which the side chains all face the same way.
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 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.
Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan.
They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic 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.
Vinyl ethers undergo homopolymerization via a cationic mechanism.
With an ever expanding product portfolio basf can satisfy your needs for functional vinyl monomers now and in the future.
Basf s global leadership in acetylene chemistry has made it the leader for development and production of functional vinyl monomers.
The main manufacturer of vinyl ether monomers and resins is basf.
Teator and leibfarth report a general protocol to polymerize a variety of such vinyl ethers isotactically see the perspective by foster and o reilly.
Poly vinyl ethers and their copolymers find many applications such as adhesives release and surface coatings lubricants greases elastomers anticorrosion agents molding.
