Polyethylene wax and its production method |
abstract |
The invention relates to a polyethylene wax and its preparation method. According to the invention, by a gas fluidized bed polymerization technology, ethene homopolymerisation or copolymerization of ethene and C3-C8 alpha-alkene is conducted by using a supported metallocene catalyst as a main catalyst, using aluminium alkyl as an auxiliary catalyst and using hydrogen as a molecular weight modifier so as to obtain the polyethylene wax. The polyethylene wax has characteristics as follows: the preparation method is simple and easy to operate; bulk density is high; molecular weight is adjustable and controllable; and molecular weight distribution is narrow. |
