Vinyl Ether Acrylate

Vinyl ether monomers can be used with acrylate oligomers to afford hybrid curable systems 13 which combine the advantages of both vinyl ether chemistry.

Vinyl ether acrylate.

It is remarkable that only 10 addition of dve 3 increases the conversion of the acrylate from about 55 to nearly 100. 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 homopolymerization via a cationic mechanism. Pubchem substance id 24867203.

Linear formula h 2 c c ch 3 co 2 ch ch 2. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. The main manufacturer of vinyl ether monomers and resins is basf. Acrylate vinyl ether radical figure 5.

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. 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 98 synonym.

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. 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 acrylate double bond polymerizes faster than the vinyl ether double bond and reaches 95 conversion in triacrylate monomers.

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. Molecular weight 112 13. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. The present invention relates to vinyl ether or acrylate terminated block resins compositions incorporating same and methods for preparing same.
