In this paper,based on a case study of an petroleum & chemical corporation in the north east of China,the environmental compatibility in polythene production is researched by using the method of life cycle assessment,and the environmental performance of contamination is identified and quantified.

Actuality and Prospect of Research and Development of Foaming Master Batch of Polyolefin;

Current Situation and Developing Tendency of Flame Retardant Polyolefin;

Advances and development proposal in single-site catalyst of polyolefin;

The market demand of poly-α-olefin(PAO) in synthetic oils was one of the fastest growing,the PAO synthetic lubricants not only have the advantage of lower volatility,higher viscosity index,lower pour point,higher flash point and excellent high temperature anti-oxidation performance,but also have long use life compared with mineral oils.

As the regulation of lubricants is becoming more and more strict, demand of high quality lubricating oils is increasing, among which most distinctly is synthetic oil, especially poly-α-olefin synthetic oil.

By employing orthogonal design L9(33),effects of polymerization temperature,catalyst quantity and reaction time on the conversion of olefins and the viscosity of poly-α-olefin lubricating base oil were studied.
