  • Patent number: 11993675
    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.

  • Patent number: 11970574
    Abstract: A method of producing an alcohol ethoxylate surfactant or lubricant, the method including reacting a low molecular weight initiator with ethylene oxide in the presence of a polymerization catalyst, the low molecular weight initiator having a nominal hydroxyl functionality at least 1, and the polymerization catalyst being a Lewis acid catalyst having the general formula M(R1)I(R2)I(R3)I(R4)0 or 1, whereas M is boron, aluminum, indium, bismuth or erbium, R1, R2, R3, and R4 are each independent, R1 includes a first fluoroalkyl-substituted phenyl group, R2 includes a second fluoroalkyl-substituted phenyl group or a first fluoro/chloro-substituted phenyl group, R3 includes a third fluoroalkyl-substituted phenyl group or a second fluoro/chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3.

  • Patent number: 11958936
    Abstract: A method of producing a polyether polyol includes reacting a low molecular weight initiator with one or more monomers in the presence of a polymerization catalyst, and the low molecular weight initiator has a nominal hydroxyl functionality of at least 2. The one or more monomers includes at least one selected from propylene oxide and butylene oxide. The polymerization catalyst is a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1, whereas M is boron, aluminum, indium, bismuth or erbium, R1, R2, R3, and R4 are each independent, R1 includes a fluoroalkyl-substituted phenyl group, R2 incudes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, R3 includes a fluoroalkyl-substituted phenyl group or a fluoro/chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3.

  • Publication number: 20100270116
    Abstract: A strap comprises an elongated flexible member and two connectors. The elongated flexible member and two connectors form two loops: a first loop that loops around a wheeled (e.g., carry-on) luggage and a second loop that loops around an item that is separate from the wheeled luggage. The second loop, in conjunction with two inter-loop connectors, secures the item to the wheeled luggage. The item may be placed on top of the wheeled luggage to provide for a more comfortable and relaxed transport of the item with the wheeled luggage.
