NON-PLASTICIZING, HIGH GLASS TRANSITION TEMPERATURE DISPERSANTS FOR MAGNETIC MEDIA |
| 摘要 |
<p>The present invention provides a non-halogenated vinyl oligomer wherein the oligomer comprises a plurality of pendant nitrile groups and at least one pendant dispersing group; wherein the oligomer has a glass transition temperature of about 60 DEG to about 105 DEG C. and a number average molecular weight of about 2000 to about 4000 and the equivalent weight of the dispersing group(s) is about 500 to about 50,000. The invention also provides magnetic recording media comprising these dispersants.</p> |
