POLYMERISATION OF MALEIC ANHYDRIDE |
| 摘要 |
Polymaleic anhydride having a weight average molecular weight by gel permeation chromatography of between 450 and 800 and a polydispersivity of between 1.0 and 1.15 is produced by polymerising malefic anhydride, using a peroxide initiator in an amount not greater than 10 % by weight of the anhydride, in a dilute solution in o-xylene or a substituted o-xylene.
