Vinyl Ether Acrylate

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics.

Vinyl ether acrylate. The main manufacturer of vinyl ether monomers and resins is basf. 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 monomers can be used with acrylate oligomers to afford hybrid curable systems 13 which combine the advantages of both vinyl ether chemistry. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers.

Vinyl methacrylate 98 synonym. 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. 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. It is remarkable that only 10 addition of dve 3 increases the conversion of the acrylate from about 55 to nearly 100.

Vinyl ethers undergo homopolymerization via a cationic mechanism. Vinyl methacrylate cas number 4245 37 8. 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. Of acrylate based oligomers low viscosity formulations permitting a wide range of application techniques safety in use high cure speeds and decreased air inhibition.

Other manufacturers of vinyl ether polymers and copolymers are ashland and idemitsu kosan. Linear formula h 2 c c ch 3 co 2 ch ch 2. Pubchem substance id 24867203. The acrylate double bond polymerizes faster than the vinyl ether double bond and reaches 95 conversion in triacrylate monomers.

New types do not contain chlorine and are less prone to mold related staining. Acrylate vinyl ether radical figure 5. Molecular weight 112 13. 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.

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.
