Abstract
PURPOSE: To obtain a polymer which is resistant to thermal and oxidative degradation and almost free from color and odor, by (co)polymerizing ethylene at high pressure and temperature by using a specified Ziegler type catalyst having extremely high activity.
CONSTITUTION: A polymer which is resistant to thermal and oxidative degratation and almost free from color and odor is produced in high yields with respect to unit transition metal and also with respect to unit carrier, by (co)polymerizing by contacting ethylene or ethylene and at least one α-olefin with a catalyst consisting of a combination of a organometallic compound or an alkylsiloxane derivative and a solid product obtained by contacting a Ti compound in which Ti is tetravalent with a magnesium dihalide, having a surface area of 5m2/g or higher before or after contact with the Ti compound, under a pressure of 200kg/cm2 or higher and a temperature of 125°C or higher.
