Similar stability and reactivity have also been observed for bridged-Cp systems. The catalyticaHy active (CH2)2Si(C (CH2)4)2ThR2, where R = Cl [89597-06-8] alkyl, CH2CgH [89597-10A] aryls, or H [89597-11-5], Similar to Group 4 transition-metal Zeigler-Natta catalysts, stable cationic Th(IV) species, eg, [Cp 2ThCH2] [108834-69-17, have been isolated with a host of noncoordinatiag/nonreactive anions. MetaHacycle formation has also been...

Control problem Given the system parameters, the control problem is to determine the controller settings for K, T and T. This will be undertaken using the Zeigler-Nichols process reaction method described in Section 4.5.5(a).

A polymer-bound hindered amine light stabilizer [P-HALS] has been synthesized by terminating the living anionic polymerization of isoprene with 4(2,3-epoxy pro-poxy)-1,2,2,6,6-pentamethylpiperidine followed by hydrogenation of the resulting polymer to E-P copolymer using Zeigler type catalyst [40] ...

West (p. 6), Miller (p. 43), Zeigler (10), and Sawan (p. 112) outline the synthesis of a wide variety of soluble, processable polydiorganosilanes, a class of polymers which not long ago was thought to be intractable. Matyjaszewski (p. 78) has found significant improvements in the synthetic method for polydiorganosilane synthesis as well as new synthetic routes to unusual substituted polydiorganosilanes. Seyferth (p. 21, 143) reports synthetic routes to a number of new polycarbosilanes and polysilazanes which may be used as precursors to ceramic materials. 

Variables in the condensation reaction include the temperature, nature of the solvent, order of addition (either chlorosilane to excess sodium or "inverse" addition, sodium to excess chlorosilane), and the rate of addition. A careful study of reaction variables by the Sandia group of Dr. John Zeigler(15) will be described in detail elsewhere in this volume. 

Photochemistry and photophysics of polysilanes is also discussed in the Chapter by Zeigler, Harrah and Johnson in this volume, ref. 15.
