摘要： Stage I Group 1 metal/porous metal oxide compositions or Stage II Group 1 metal/porous metal oxide compositions are shown to be useful to remove impurities and act as drying agents for various types of solvents and for olefinic monomers used in anionic polymerizations. One important advantage of these compositions is their ability to dry simultaneously solvent and monomers, without inducing a significant polymerization of the latter. Another important characteristic is the capacity of the compositions to be totally inactive toward conventional anionic polymerization which allows them to be left in situ during the polymerization itself.
摘要翻译： 阶段I第1族金属/多孔金属氧化物组合物或II级第1族金属/多孔金属氧化物组合物被证明可用于除去杂质并用作各种类型的溶剂和用于阴离子聚合的烯烃单体的干燥剂。 这些组合物的一个重要优点是它们能够同时干燥溶剂和单体，而不会引起后者的显着聚合。 另一个重要的特征是组合物对于常规的阴离子聚合完全无活性的能力，这允许它们在聚合本身期间留在原位。
