A composition having the formula: wherein R is a linear alkyl, branched alkyl, cycloalkyl, polycyclic alkyl, alkylaminoalkyl, or alkyloxyalkyl group having 1 to 20 carbon atoms and at least one primary, secondary, or tertiary amino functional group. The composition is effective as a catalyst in the production of polyurethanes.

Polymerizable ester surfactant, or a salt thereof, having the formula: wherein: R is an optionally substituted vinyl radical, R is a divalent polyoxyalkylene radical having at least two oxypropylene units, optional oxyethylene units in a block or random pattern, and a molar ratio oxypropylene units to oxyethylene units of at least about 2:1, preferably at least about 3:1, typically at least about 4:1 and more typically at least about 5:1, and X is a phosphate group, wherein in the ester the mono-phosphate ester to di-phosphate ester weight ratio is greater than 80:20. These polymerizable surfactant compounds are useful as the sole surfactant in producing polymer latices by emulsion polymerization by polymerization of them with another polymerizable monomer.

A method for making a polyether monomer having at least one unsaturated site per molecule and having a desired number of alkoxyl repeating units includes the steps of reacting an active hydrogen-containing monomer having at least one unsaturated site per molecule with an alkyl oxide in the presence of an alkoxylation catalyst and a polymerization inhibitor at a temperature from about 30 C. to less than 45 C. to produce a polyether monomer. In one embodiment, from about 5 to about 1000 parts by weight of a phenothiazine polymerization inhibitor per one million parts by weight of the active hydrogen-containing monomer phenothiazine compound is used as the polymerization inhibitor.

A heterogeneous two component waterborne urethane/vinyl polymer composition, the method of making the composition, and the coating derived therefrom. The composition is a low or zero VOC composition containing a polyol stabilized non-functional, high Tg, aqueous vinyl polymer latex, a water dispersible polyisocyanate, and, optionally, a polyhydric alcohol. The composition is formed by emulsion polymerizing one or more vinyl monomers which will form a high Tg polymer, in the presence of an emulsifier containing one or more acid-containing polyols which have been neutralized with one or more reactive amines, and combining the resulting polyol-stabilized high Tg aqueous vinyl polymer latex with a water-dispersible polyisocyanate and, optionally, a polyhydric alcohol.

Systems and methods for pacing data transmission are described. An illustrative method includes transmitting, by a network device, a data stream at a pacing rate to a user equipment (UE) device. The method further includes accessing a metric of a radio access network (RAN) to which the UE device is connected, the metric associated with the UE device. The method further includes adjusting, based on the metric, the pacing rate at which the data stream is transmitted to the UE device.
