Vinyl Ether Acrylate

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 ether acrylate.

Some commercially important vinyl ethers include ethyl n butyl isobutyl ethylhexyl dodecyl octadecyl and cyclohexyl vinylether. New types do not contain chlorine and are less prone to mold related staining. 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. Acrylic elastomer can generally be characterized as one of two types.

Pubchem substance id 24867203. The acrylate double bond polymerizes faster than the vinyl ether double bond and reaches 95 conversion in triacrylate monomers. Acrylate vinyl ether radical figure 5. It is remarkable that only 10 addition of dve 3 increases the conversion of the acrylate from about 55 to nearly 100.

The present invention relates to vinyl ether or acrylate terminated block resins compositions incorporating same and methods for preparing same. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Of acrylate based oligomers low viscosity formulations permitting a wide range of application techniques safety in use high cure speeds and decreased air inhibition. Vinyl methacrylate 98 synonym.

Vinyl ether monomers can be used with acrylate oligomers to afford hybrid curable systems 13 which combine the advantages of both vinyl ether chemistry. Molecular weight 112 13. 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. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers.

Vinyl methacrylate cas number 4245 37 8. 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. Vinyl ethers undergo homopolymerization via a cationic mechanism. Linear formula h 2 c c ch 3 co 2 ch ch 2.
