PROCESS FOR PREPARING LIGHT COLORED PETROLEUM RESINS AND RESINS PRODUCED THEREBY |
摘要 |
<p>Petroleum resins of lightened color while retaining satisfactory melting point and compatibility are provided by a process which comprises heat soaking a petroleum cracking or reforming fraction containing cationically polymerizable hydrocarbons and from 2 to more than 0.5 weight percent of cyclodienes until the cyclodiene content is no more than 0.5 weight percent, disitilling said heat soaked petroleum fraction and polymerizing said distilled petroleum fraction in the presence of a polymerization catalyst.</p> |
