| titleOfInvention | Methods of preparing polymers having terminal amine groups using protected amine salts |
| abstract | The present invention is directed to methods of preparing linear polymers such as polyalkylene oxides containing a terminal amine in high purity. One preferred method includes reacting a polyalkylene oxide such as polyethylene glycol containing a terminal tosylate with a protected amine salt to form a polymer containing a terminal protected amine and thereafter deprotecting the polymer containing the terminal protected amine to form the polymer having a terminal amine. The resultant polymer-amines are of sufficient purity so that expensive and time consuming purification steps required for pharmaceutical grade polymers are avoided. |
