Vinyl Ethers Materials

The company started manufacturing in 1984 and remodeled facilities in 1996.

Vinyl ethers materials.

The company has been manufacturing and selling vinyl ethers having a range of functions from low boiling point vinyl ethers to polyfunctionalized divinyl ethers. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Vinyl ethers are well established as radiation curable materials exhibiting a wide diversity of chemistry 1. In this work we have developed a versatile and highly efficient initiation approach based on thienyl chloride derivatives with readily available starting materials for the living cationic polymerization of vinyl ethers.

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. It is prone to polymerization leading to formation of polyvinyl ethers. Their glass transition temperature is well below room temperature. For their elasticity and excellent resistance to hydrolysis being ether based pves do not hydrolyze.

The right hand lines up vinyl ethers well optimized catalysts produce vast quantities of isotactic polypropylene in which the side chains all face the same way. These materials possess several attractive features such as low toxicity and high reactivity. Polymerization is typically initiated with lewis acids such as boron trifluoride. The alkene portion of the molecule is reactive in many ways.

Is used as raw material for weather resistant coatings and has a good record of use for bridges and. A good selection of reactive monomers and prepolymers is commercially available. Ethyl vinyl ether is made by reaction of acetylene and ethanol in presence of a base. Poly vinyl ether s pves are useful materials of different applications.

Add an oxygen into the monomer. Vinyl ethers undergo homopolymerization via a cationic mechanism. Vinyl ethers 1 which have a strongly electron donating alkoxy substituent readily form polymers on treatment with an acidic compound initiator.
