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.

Recent progress in the immobilization of non-metallocene olefin polymerization catalyst;

Characterization techniques for the morphology of supported catalyst and nascent polymer particles in olefin polymerization;

Study on the Chain initiation for Olefin Polymerization with Neutral Salicylaldiminato Nickel(II) Catalyst by Density Functional Theory;

The air compressor oils of reciprocating type were developed by taking polyalphaolefin(PAO)/API Group Ⅱ and/or Ⅲ base oils from hydrocracking process and ester-based synthetic fluids as base oils,and adding proper rust & oxidation inhibitors,anti-wear additive and metal deactivator.

Comparing with mineral oil, Poly-Alpha-Olefins(PAO)offer a lot of advantages including better viscosity-temperature coefficient, lower pour point, higher viscosity index, excellent heat anti- oxidation etc and are thus widely recognized.

The process of taking PAO as base oil and adding domestic additives to formulate the premium rolling oils for aluminum was described,and the results of cold rolling mill test was given.
