균일계 티타늄 촉매를 이용한 결정성 폴리에틸렌 왁스의 중합에서 중합온도, 중합 시간, 공촉매, 수소분압, 공단량체 등의 중합인자가 촉매성능과 폴리에틸렌 왁스의 물성(분자량, 분자량 분포, 밀도, 결정화도 등)에 미치는 영향을 조사하였다. (C₂H_5)₃Al, (i-C₄H_9)₃Al, (C₂H_5)₂AlCl, (C₂H_5)₃Al₂Cl₃을 사용하여 공촉매의 영향을 조사한 결과 (C₂H_5)₃Al/(C₂H_5)₃Al₂Cl₃의 혼합 공촉매계가 가장 효과적이었다. 중합시간, 중합온도, 수소분압은 촉매의 활성과 생성 폴리에틸렌 왁스의 물성에 영향을 주고, 이러한 중합인자의 조합에 의해 다양한 물성을 갖는 결정성 폴리에틸렌 왁스를 얻을 수 있음을 확인할 수 있었다. 또한 부텐-1과의 공중합에 의해 0.91g/cc까지의 저밀도형 왁스를 얻을 수 있었다.

In the polymerization of ethylene to produce crystalline polyethylene wax using the homogeneous titanium-based catalyst, the effects of various parameters such as cocatalyst, temperature, pressure, comonomer and time on the performance of catalyst and the properties of polyethylene wax were investigated. The properties of polyethylene wax obtained were characterized in terms of molecular weight, molecular weight distribution, crystallinity, density and morphology. Among the polymerization features with a series of mixed cocatalyst systems of (C₂H_5)₃Al, (i-C₄H_9)₃Al, (C₂H_5)₂AlCl and (C₂H_5)₃Al₂Cl₃, it turned out that the combination of (C₂H_5)Al and (C₂H_5)₃Al₂Cl₃ was more effective than any other combination. It was noted that the activity of catalyst and the properties of polyethylene wax were affected by the polymerization parameters, i.e. time, temperature and hydrogen partial pressure. The various kinds of crystalline polyethylene wax could be obtained by careful control of these parameters. Also we could obtain low density polyethylene wax which has density down to 0.91 g/cc by use of 1-butene as a comonomer.
