A process for the conversion of methanol to olefins includes the steps of passing a feedstock comprising methanol to a fluidized bed reactor in contact with a catalyst to produce an olefin product, wherein the process at least partially deactivates the catalyst to form an at least partially deactivated catalyst; and passing spent catalyst from said at least partially deactivated catalyst to a regenerator for regeneration thereby forming regenerated catalyst and returning activated catalyst from said regenerated catalyst to said reactor via a regenerated catalyst line. An oxygen volume content in the gas-phase component at the outlet of the regenerated catalyst pipeline is controlled to be less than 0.1 percent, preferably less than 0.05% and more preferably less than 0.01% on the regenerated catalyst pipeline.

A method is described for producing a polyether polymer, in which side reactions are suppressed to increase the thiol group content without adding hydrogen sulfide, and the halogen content is reduced. A method is also described for producing a thiol group-containing polyether polymer by reacting a terminal halogenated polyether polymer and a hydrogen sulfide metal salt by a substitution reaction, in which the substitution reaction is performed in a closed system, the terminal halogenated polyether polymer is charged into a closed system in an amount of 20 vol % or more of a volume of the closed system, and the hydrogen sulfide metal salt is charged into the closed system as an aqueous solution having a concentration of 25 mass % or more.

An object of the present invention is to provide a gel material including a solvophilic polymer having a m-scale porous structure. A polymer gel in which solvophilic polymer units are cross-linked with each other, wherein the polymer gel contains a solvent and has a three-dimensional network structure having two regions: a first region in which the polymer units are densely present and a second region in which the polymer units are sparsely present, and a mesh size composed of the first region is from 1 to 500 m.

Waterborne coatings are described having an acceptable balance of properties both during the storage of coating, application and drying. The period in which irregularities in a freshly applied coating can be repaired without resulting in brush marks is referred to as the open time. Aqueous coatings generally employ dispersed high molecular weight polymers as binders. These binders often provide short open times when the coating is dried since the dispersed polymer particles tend to be immobilized quickly in the edge region of an applied coating. As a result, the viscosity of the coating increases rapidly, which leads to a limited window of workability. The instant invention provides additives that are not volatile but that will extend the time that the film is malleable after it is applied without interfering with other attributes, such as the resistance of the coating to freezing while in the can prior to application.
