Bimetallic Al(III) catalysis mediates thioanhydride/epoxide copolymerisation at greatly improved rates and monomer tolerance than analogous Cr(III) catalysis. Moving to sulfurated monomers furthermore generally improves rates and selectivites.

通过异双金属铝催化改善聚硫酯的制备

与类似的 Cr( III ) 催化相比，双金属 Al( III ) 催化以大大提高的速率和单体耐受性介导硫代酸酐/环氧化物共聚。此外，转向硫化单体通常还可以提高速率和选择性。
