MOLECULAR-WEIGHT MODIFICATION OF POLYPHOSPHAZENES |
| 摘要 |
<p>A novel process has been developed for the molecularweight modification of polyphosphazenes. Poly(aryloxyphosphazenes) are thermally treated in an inert atmosphere or vacuum at temperatures from 100.degree.C. to 300.degree.C. so as to yield materials having reduced molecular weights, improved processability, and enhanced thermal stability.</p> |
