WebWhen polymerization of isobutyl vinyl ether is carried out at temperatures in the range of — 80°C using boron trifluoride etherate as initiator, isotactic crystalline polymer can be produced. Ethyl and isobutyl ethers produce polyvinyl ethers with low 7 s, and are used in pressure-sensitive adhesives. Ethyl vinyl ether is made by reaction of acetylene and ethanol in presence of a base. The alkene portion of the molecule is reactive in many ways. It is prone to polymerization, leading to formation of polyvinyl ethers. Polymerization is typically initiated with Lewis acids such as boron trifluoride. Ethyl vinyl ether participates in many reactions of interest to organic synthesis. With catalytic am…
WebThermoplastic. A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt to a liquid.
