多孔有机聚合物中试制备及其在聚烯烃催化剂中的应用
Pilot scale production of porous organic polymers and their application in polyolefin catalysts
摘要
Abstract
Porous organic polymers(POPs)are widely used in many fields such as adsorption,separation and catalysis.In this research,pilot scale POPs(POP3120T and POP3100)were produced by via of dispersion polymerization,which exhibited excellent flowability and surface morphology.High specific surface area(SSA of 282m2/g),bulk density(0.29g/cm3)of POP3120T with average particle size of 23.4μm(PSD:1.0)were obtained,which was comparable to inorganic silica gel support.POP3100 obtained higher SSA of 503m2/g with average particle size of 36.0μm(PSD:0.93).The supported Z-N@POP PP catalysts exhibited good polymerization activity above 1.0×107gPP/(mol Ti·h),high bulk density of 0.36g/cm3 and low fine powder content(≥100 mesh,＜1%),which was equal to the level of commercial PP catalysts.Furthermore,the supported Z-N@POP PP catalysts showed high stereoregularity with isotacticity index above 97.5%and broad molecular weight distribution above 11.关键词
