POW scale of production could not meet the mar- ket demand in China,especially the high-grade polyolefin wax is dependent on imports basically,and it should be devel- oped and produced accelerately.

The study of polyethylene wax oxidation and graft modification

NaA zeolite membranes were synthesized hydrothermally on the surface of macroporous supports with polypropylene wax preoccupying the pores.

Data indicated that the values of interfacial shear strength of specimen which glass fiber coated with a silane coupling agent and grafted or ungrafted polypropylene wax would be elevated remarkably than that of the composite which glass fiber treated with the.

The rheological properties of HDPE 5000S containing lanthanides stearate or compounds of lanthanum stearate and lanthanides stearate /PE-wax blends were studied by means of constant rate and constant pressure rheometer.

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.
