1,1-Bis(diphenylphosphino)ethylene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Sample 6 was the same as Sample 5 with a couple of exceptions. Ingredient 4, DTHFP/hexane, was added at 0.37 kg/hr (0.10 M DTHFP). An additional ingredient, VDPP/hexane (0.18 kg/hr, 0.2 M VDPP) was mixed with ingredients 3, 4, 5, and 6 and allowed to mix for about 14 minutes prior to entering the bottom of the reactor. Polymer properties for Sample 6 were 33 ML4, 2.3 sec t-80, and 99.7% conversion. to mix for about 14 minutes 33 ML4, 2.3 sec t-80, and 99.7% conversion
