Polyphosphazene polymers containing cyanamido or dicyanamido substituents |
| 摘要 |
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: <IMAGE> wherein X and X' are the same or differnt and are represented by: <IMAGE> wherein R1 is selected from a group consisting of hydrogen and-CN; X' may additionally be selected from the group consisting of substituted and unsubstituted alkoxy, aryloxy, mercapto and amino groups and 20 </=(w +y+z) </=50,000 per polymer. The polymers of the invention can be utilized to form protective films and can also be utilized in applications such as for molding, coatings, foams and the like.
