摘要: 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.

摘要: The present invention is method comprising the steps of a) contacting 4-hydroxyphenone and a salt thereof with propylene oxide in a reactor heated to a temperature in the range of from 100° C. to 200° C. to form a poly(propylene oxide)-benzophenone intermediate; then b) contacting the intermediate with ethylene oxide in the heated reactor to form an alkoxylated benzophenone substituted with propylene oxide groups and ethylene oxide groups. The method of the present invention is useful for preparing a non-volatile alkoxylated benzophenone photoinitiator that gives long lasting gloss retention in an exterior architectural coating.

IPC分类号: C08G65/26
摘要: Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a cyclic amidine. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of cyclic amidine greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.
