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.

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.
