    摘要： Low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of a base polyol having a molecular weight higher than 4000, for example, from 4000 to 6500 and a high molecular weight (HMW) dispersant. The dispersant polyol may range from 1 to 20 wt. %, but may be less than 5 wt. % of the total polyol component of the polymer polyol. The HMW dispersant should have a molecular weight higher than about 6000. Preferably, a semi-batch reactor is used, and a relatively high concentration of the HMW dispersant is initially charged to the reactor, relative to the portion of base polyol. Monomer ratios of styrene to acrylonitrile of 85/15 may be achieved with this method.

    摘要： A class of mixed oxide catalysts comprising Mn-containing oxides, alkali metals or compounds thereof, and at least one member of the group consisting of oxides of Ti, mixed oxides of Ti and Si, and mixed oxides of Ti and at least one alkaline earth metal. In the more preferred embodiments, the third component serves as a carrier for the Mn and alkali metal components. The composition preferably comprises a major amount of the carrier material and minor amounts of the other components. The compositions are useful for hydrocarbon conversion, methane conversion, and oxidative dehydrogenation processes characterized by formation of coproduct water.

    摘要： Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy modified polyols as dispersants. The epoxy modified polyols useful as dispersants may be made by one of three methods: (1) adding the epoxy resin internally to the modified polyol, (2) capping or coupling a polyol not containing an epoxy resin with such a resin, and (3) providing the epoxy resin both internally to the polyol and as a cap or coupler. Epoxy modified polyols having a hydroxyl to epoxy ratio of about 8 or less, made by one of these techniques, are superior dispersants and provide polymer polyols having higher styrene contents, and improved stability and viscosity properties. In one aspect, the epoxy modified polyols contain a significant amount of high moleular weight polyol adducts; generally from about 5 to about 30 wt. % of materials having a GPC molecular weight of greater than 100,000; and at least greater than 80,000. Base polyols unmodified with an epoxy resin are used to make the polymer polyols.

    摘要： Low viscosity polymer polyol polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of a high molecular weight (HMW) dispersant polyol comprising less than 5 wt. % of the total polyol component of the polymer polyol. The HMW dispersant should have a molecular weight higher than about 6000. Preferably, a semi-batch reactor is used, and a relatively high concentration of the HMW dispersant is initially charged to the reactor, relative to the portion of base polyol, which has a molecular weight of less than 4000.

    摘要： Processes for making poly(thioether ether)s and hydroxy-terminated poly(thioether ether)s are disclosed. The poly(thioether ether)s are made by bulk free-radical polymerization of diallyl ether and an aliphatic C.sub.2 -C.sub.10 dithiol. Liquid polymers are obtained when mixtures of two or more dithiols are used. Hydroxy-terminated products are obtained by reacting the poly(thioether ether)s with allyl alcohol under free-radical conditions.
