Abstract
A process for the preparation of a maleated polyethylene wax is disclosed. This process entails mixing in the melt phase polyethylene, maleic anhydride, free radical initiator and a chain transfer agent m-di-isopropylbenzene. This process can be a continuous process either in a stirred reactor or twin screw extruder. The resulting maleated polyethylene wax has a high acid number, essentially no objectionable odor, and a Gardner color number less than 3.
