Vinyl Ether Acrylates
Some commercially important vinyl ethers include ethyl n butyl isobutyl ethylhexyl dodecyl octadecyl and cyclohexyl vinylether.
Vinyl ether acrylates. Uv curable coating technology provides benefits in terms of good performance environmental compatibility and processing efficiency. New types do not contain chlorine and are less prone to mold related staining. Vinyl ethers undergo homopolymerization via a cationic mechanism. Employing either radical or cationic curing mechanisms the crosslinking of these coatings is initiated by means of uv light.
The main manufacturer of vinyl ether monomers and resins is basf. Vinyl methacrylate 98 synonym. Vinyl methacrylate cas number 4245 37 8. Cyclopolymerization of a divinyl monomer where two different vinyl groups that is acrylate and vinyl ether are connected via an ester bond was performed under diluted condition with nitroxide meditated radical polymerization nmp.
Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Old types include acm copolymer of acrylic acid ester and 2 chloroethyl vinyl ether containing chlorine and anm copolymer of acrylic acid ester and acrylonitrile without chloride. Styrene and monomeric acrylates are well known as reactive diluents in uv formulations.
Copolymerization with acrylates utilizes free radical emulsion techniques. Linear formula h 2 c c ch 3 co 2 ch ch 2. Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan. Molecular weight 112 13.
Both vinyl groups were consumed at almost same rate under suitable condition although the inherent cross propagation ability between the two vinyl groups are. 47 vinyl ether homopolymers are produced by cationic solution polymerization. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed granted application number ep85103419a other versions. This article reviews the use of vinyl ether vinyl amid and vinyl ester compounds in the formulation of uv curing coatings in graphic arts wood and plastic coating applications.
The vinyl group is susceptible to polymerization and the. Prop 2 enoates are the salts and esters and conjugate bases of acrylic acid the acrylate ion is the anion c h 2 chcoo often acrylate refers to esters of acrylic acid the most common member being methyl acrylate these acrylates contain vinyl groups these compounds are of interest because they are bifunctional. Vinyl ether containing compounds urethane acrylates ether containing prior art date 1984 03 23 legal status the legal status is an assumption and is not a legal conclusion. Acrylic elastomer can generally be characterized as one of two types.
