Usage tert-Butyl vinyl ether is used in the synthesis of 3-tert-Butoxycyclobutanone by reacting with ketene using zinc(II) chloride as a catalyst. It acts as an intermediate for the functional vinyl monomer. Manufacturing Info Propane, 2-(ethenyloxy)-2-methyl-: ACTIVE...
Sealant and potting formulations are provided which includes ungelled polymer(s) prepared from components including polyvinyl ether monomer(s) and polythiol materials(s), the ungelled polymer being terminated with functional groups other than a thiol group; curing agent(s); and at least one additive...
[0010] The carboxyl group-containing ethylene-acrylic copolymer rubber of the present invention is preferably obtained by copolymerizing the above carboxyl group-containing unsaturated aliphatic acid and an unsaturated monomer such as an acrylic acid alkyl ester. [0011] Examples of the acrylic acid ...
When a chiral initiator is employed with a racemic mixture of such a monomer, one enantiomer (either R- or S-monomer) may be polymerized selectively, with another enantiomer left unchanged, to give an optically active polymer. For vinyl ethers, however, a highly asymmetric-selective ...
