Branched chain microwax prodn. from polypropylene |
| 摘要 |
<p>The prodn. of branched chain microwax (I) from polypropylene (PP) of the high-mol. wt. intermediate degradation prods. (d-PP) obtd. by mild thermal treatment of PP comprises cracking at 390-450 deg C in the absences of oxygen with simultaneous distn. of the cracking prods. at 1-100 (pref. 1-30) mbar, followed by selective de-oiling of the distillate using known processes.</p> |
