摘要:
Process for the preparation of polyolefin-substituted succinic anhydrides essentially free from chlorine and in which the average molar ratio of succinic groups to polyolefin chains is greater than 1.3:1, which comprises heating a polyolefin with a molar excess of maleic anhydride, the polyolefin containing at least 70% of the terminal groupings in a structure having an alpha olefinic bond and/or structures in equilibrium with such alpha olefinic structures.
