Abstract: | The synthesis of various phosphoranimines including (CH3OCH2CH2O) (CF3CH2O)2P?N? Si(CH3)3, (CH3OCH2CH2OCH2CH2O) (CF3CH2O)2P?N? Si (CH3)3, (CH3OCH2CH2O)2(CF3CH2O) P?N? Si(CH3)3, and (CH3OCH2CH2OCH2CH2O)(CF3CH2O) P?N? Si(CH3)3 via the Staudinger reaction of (CH3)3SiN3 with the suitably substituted phosphite is reported. These monomers were polymerized using tetra-n-butylammonium fluoride and N-methylimidazole in various solvents at several temperatures. In situ 31P-NMR kinetic studies and Mn versus time studies were also performed for the monomers to understand the propagation mechanism. © 1994 John Wiley & Sons, Inc. |
