Ferric acetyl acetonate

Amorphous (most likely atactic) 3,4-polyisoprene of 94—100% 3,4-microstmcture was prepared with a (C2H 3A1—Ti(0—/ -C Hy) catalyst (11). Crystalline 3,4-polyisoprene containing about 70% 3,4-units and about 30% i7j -l,4-microstmcture was prepared using a catalyst derived from iron acetyl acetonate, trialkyl aluminum, and an amine in benzene (37). However, this polyisoprene contained gel and was obtained in poor yield. Essentially gel-free crystallizable 3,4-polyisoprene of 70—85% 3,4-microstmcture with the remainder being cis-1,4 microstmcture was prepared in conversions of greater than 95% with a water-modified tri alkyl aluminum, ferric acetyl acetonate, and 1,10-phenanthroline catalyst (38). The 3,4-polyisoprene is stereoregular and beheved to be syndiotactic or isotactic. [Pg.4]

Examples of the components of the gelling composition are a water-soluble polymer such as polyacrylamide, an iron compound such as ferric acetyl-acetonate or ammonium ferric oxalate, and a ketone such as 2,4-pentanedione [1247]. The composition forms a temporary gel that is useful for the temporary plugging of a formation. The temporary gels that are formed will disappear after 6 months. [Pg.113]

Anotner organic ferric compotuid,namely the ferric acetyl acetonate (PemAcAo) has been found to be an effective initiator for the photodegradation of polyethylene (65) and poly(vinyl chloride)(66). These ferric compounds are easily oxidized and photolyz eT. The following mechanism for radical formation in polyethylene sample was proposed (67,68)1... [Pg.261]

There are many other iron complexes of a similar nature yet to be investigated including many model complexes such as cupferron and ferric acetyl acetonate as well as the hydroxamates and the catechols. [Pg.96]

Evaluating a single catalyst, the fastest cure rate is when ferric acetylacetonate is used in the system. In high concentrations, cobalt napthanate alone and combined with cobalt octoate, offer a fast reaction rate. Yet, when ferric acetyl acetonate is combined with cobalt napthanate or cobalt octoate, the reaction rate increases. For this system, the increased amount of catalyst yields a decrease in cure time. There is no direct correlation between length of time specimens were was subjected to heat and cure rate. [Pg.413]
