    摘要： Disclosed is a process for preparation of final graft polyols via a continuous process. In, addition, a final graft polyol formed by the process is disclosed. The process includes the steps of reacting a plurality of ethylenically unsaturated monomers and a reaction moderator with a macromer having induced unsaturation in the presence of a carrier polyol, a free radical polymerization initiator, and a first graft polyol. The process provides for the preparation of a final graft polyol having a solids level of from 30 to 70% in a continuous process. The final graft polyol produced by the process has a lower viscosity over a range of solids levels, a reduced amount of very large irregularly shaped particles, a reduced viscosity change in response to a change in reaction temperature compared to a typical graft polyol, a reduced tendency to foul the continuous reactor, and a broader particle size distribution compared to an identical graft polyol prepared by a semi-batch process.

    摘要翻译： 公开了通过连续方法制备最终的接枝多元醇的方法。 另外，公开了通过该方法形成的最终的接枝多元醇。 该方法包括以下步骤：在载体多元醇，自由基聚合引发剂和第一接枝多元醇的存在下使多个烯属不饱和单体和反应缓和剂与具有诱导的不饱和度的大分子单体反应。 该方法提供在连续方法中制备固体含量为30至70％的最终接枝多元醇。 通过该方法生产的最终的接枝多元醇在固体含量范围内具有较低的粘度，减少了非常大的不规则形状的颗粒的量，响应于与典型的接枝多元醇相比反应温度的变化而降低的粘度变化， 与通过半间歇法制备的相同的接枝多元醇相比，污染连续反应器的倾向和更宽的粒度分布。

    摘要： The instant invention relates to an apparatus for treating wastewater containing bentazon by decomposing the bentazon therein and thus eliminating or substantially reducing the bentazon content. This apparatus includes means for adjusting the pH of the wastewater to a value of less than 7 and heating it to a temperature of at least about 60.degree. C.

    摘要： A process is disclosed for formation of a preformed stabilizer for use in formation of graft polyols. The preformed stabilizer has a reduced level of transesterification products and results in less reactor fouling. The preformed stabilizer is prepared in the presence of phosphorous compounds, which reduces the unwanted transesterification products.

    摘要： A process of forming a polyol includes the step of providing an initiator composition. The initiator composition includes sucrose as a first initiator and glycerin as a second initiator. The process also includes the steps of providing a dimethylalkanolamine and providing an alkylene oxide. The process further includes the step of reacting the initiator composition, the dimethylalkanolamine, and the alkylene oxide at a pressure of at least 60 psig to form the polyol. After formation, the polyol is utilized in a process of forming a polyurethane article. The process of forming the polyurethane article includes the steps of providing an isocyanate component and providing the polyol. The process of forming the polyurethane articles also includes the step of reacting the isocyanate component and the polyol to form the polyurethane article. The polyurethane article includes the reaction product of the isocyanate component and the polyol.
