  H-膦酸酯二烷基酯与脂肪醇的连续流醇解。

  摘要：

  使用配备有流通池的微波（MW）反应器，可以在不存在催化剂的情况下，通过脂肪族醇对H-膦酸二烷基酯的连续流动进行醇解。通过精确控制反应条件，可以将合成微调为具有两个不同且具有两个相同烷基的H-膦酸二烷基酯。与“传统的”批量醇解相反，流动方法需要更短的反应时间，并且产物可以大规模使用。

  The instant invention teaches a method for forming a syndiotactic 1,2-polybutadiene product having a syndiotacticity of more than 66.5 % and a melting temperature of more than about 100°C. The method includes polymerizing 1,3-butadiene in solution with a solvent, in the presence of catalytically effective amounts of: (a) an organomagnesium compound; (b) a chromium compound; and, (c) a dihydrocarbyl hydrogen phosphite. The present invention also contemplates a product of the method and an article made from the product.

• Process and iron-based catalyst composition for the production of syndiotactic 1,2-polybutadiene

  A catalyst composition comprising (a) an iron-containing compound, (b) a dihydrocarbyl hydrogen phosphite, and (c) an organoaluminum compound is disclosed for polymerizing 1,3-butadiene into syndiotactic 1,2-polybutadiene. The use of the catalyst composition of this disclosure avoids the use of environmentally detrimental components such as carbon disulfide and halogenated solvents. The melting temperature of the syndiotactic 1,2-polybutadiene can be varied from about 100 to about 200 °C by variations in the catalyst components and the component ratios. The ability to vary the melting temperature over such a broad range with a single catalyst composition is very desirable. The syndiotactic 1,2-polybutadiene can be used as a plastic or as an additive for rubber compositions wherein it can crosslink with conventional rubbers using conventional crosslinking agents.

  本发明公开了一种催化剂组合物，该催化剂组合物包括(a)含铁化合物，(b)二氢羰基亚磷酸氢酯和(c)有机铝化合物，用于将 1,3-丁二烯聚合成对位 1,2-聚丁二烯。使用本公开的催化剂组合物可以避免使用二硫化碳和卤代溶剂等有害环境的成分。通过改变催化剂组分和组分比例，辛二聚丁二烯的熔化温度可在约 100 至约 200 °C 之间变化。使用单一催化剂成分就能在如此大的范围内改变熔化温度是非常理想的。辛二聚丁二烯可用作塑料或橡胶组合物的添加剂，其中辛二聚丁二烯可使用常规交联剂与常规橡胶交联。
