Vinyl Ether Acrylate

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.

Vinyl ether acrylate.

Vinyl ethers undergo homopolymerization via a cationic mechanism. The acrylate double bond polymerizes faster than the vinyl ether double bond and reaches 95 conversion in triacrylate monomers. In particular the compositions of the present invention may contain a vinyl ether or acrylate terminated block resin such as a polyurethane block copolymer a reactive diluent having vinyl ether or 1 alkenyl ether and meth acrylate functionality. Vinyl methacrylate cas number 4245 37 8.

Linear formula h 2 c c ch 3 co 2 ch ch 2. Vinyl methacrylate 98 synonym. Some commercially important vinyl ethers include ethyl n butyl isobutyl ethylhexyl dodecyl octadecyl and cyclohexyl vinylether. The present invention relates to vinyl ether or acrylate terminated block resins compositions incorporating same and methods for preparing same.

Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan. 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. Vinyl ether acrylate hybrids were also found to polymerize readily upon uv exposure in the presence of a radical photoinitiator according to a cross propagation mechanism which generates a copolymer with isolated ve. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics.

Molecular weight 112 13. Polymerization rate in figure 5 the conversion of acrylate 1407 cm 1 and vinyl ether groups 1618 cm 1 are plotted as a function of vinyl ether content. Of acrylate based oligomers low viscosity formulations permitting a wide range of application techniques safety in use high cure speeds and decreased air inhibition. Pubchem substance id 24867203.

They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Vinyl ether monomers can be used with acrylate oligomers to afford hybrid curable systems 13 which combine the advantages of both vinyl ether chemistry. New types do not contain chlorine and are less prone to mold related staining. Acrylic elastomer can generally be characterized as one of two types.

The main manufacturer of vinyl ether monomers and resins is basf.
