Abstract: A method of producing a polyether alcohol that includes feeding an initiator into a reactor, feeding one or more monomers into the reactor, feeding a polymerization catalyst into the reactor, the polymerization catalyst being a Lewis acid catalyst having a general formula M(R1)1(R2)1(R3)1(R4)0 or 1, separate from feeding the initiator into the reactor, feeding a hydrogen bond acceptor additive into the reactor, the hydrogen bond acceptor additive being a C2 to C20 organic molecule having at least two hydroxyl groups, of which two hydroxyl groups are situated in 1,2-, 1,3-, or 1,4-positions on the organic molecule, and allowing the initiator to react with the one or more monomers in the presence of the polymerization catalyst and the hydrogen bond acceptor additive to form a polyether alcohol having a number average molecular weight greater than a number average molecular weight of the initiator.

Abstract: An apparatus configurable between a stowed or collapsed position against a support surface (e.g., wall) and a deployed position extending from the support surface for support of objects thereon. The apparatus is configured to make simultaneous use of first and second perpendicular pivot axes to both rotate the apparatus about the first pivot axis through the support surface and pivot first and second pieces of the apparatus relative to each other about the second pivot axis as the furniture system moves between the stowed and deployed positions. This ergonomic and balanced arrangement advantageously allows users to move the apparatus between the stowed and deployed positions with reduced levels of effort.
