Aminopropyl-terminated polydimethylsiloxane

Some characteristics of aminopropyl terminated polydimethylsiloxane oligomers are illustrated in Scheme 5. 

An interesting variation of an ammonium silanolate catalyst was described by Hoffman and Leir40. They prepared tetramethylammonium 3-aminopropyldimethylsilanolate and used it to synthesize 3-aminopropyl terminated Polydimethylsiloxane (PDMS).

The synthesis of amine terminated polysiloxane (PSX) (3) has been reported elsewhere. Aminopropyl terminated polydimethylsiloxanes with s of 1070 and 2670 mole, as determined by potentiometric titration, were used. The synthesis of high molecular weight polyimides er capped with phthalic anhydride (PA) has also been reported(3). 

Potentiometric titration The s of the aminopropyl terminated polydimethylsiloxanes were determined by potentiometric titration with HCI on a MCI Automatic Titrator GT-05.
