Abstract

Aminopropyl-terminated poly(dimethylsiloxane) (ATPS) with different molecular weights was prepared by base-catalyzed equilibration of octamethylcyclotetrasiloxane and 1,3-bis(3-aminopropyl)-1,1,3,3-tetramethyldisiloxane with different ratios. Their number-average molecular weights (Mn) were determined by end–group analysis, and intrinsic viscosity ([η]) in toluene was measured with a Ubbelohde viscometer. A relationship between Mn and [η] was obtained for ATPS. For 1.0 × 104 < Mn < 6.0 × 104, it was in accord with [η]toluene,25°C = 5.26 × 10−2Mn0.587. © 2001 John Wiley & Sons, Inc.
