摘要

研制不同组分的载体钛系高效催化剂

考察在不同聚合条件及外加芳酯的情况下对1-丁烯聚合的影响。用催化剂TiCl4

Ti(OBu)4/φ2SiCI2/苯甲酸乙酯(EB)/MSCl2/AlEt3进行1-丁烯聚合具有高的催化活性(3.2×104g·PB/g·Ti·h)

外加对-甲基苯甲酸乙酯时可提高聚合物等规度(Ⅰ.Ⅰ％=93.3)

分子量可用H2调节。衰减聚合反应的动力学方程为R1=R5+(R0-R5)eβt。用DSC、WAXD和13C-NMR等方法表征聚合物。

Abstract

1-Butene was polymerized with highly active supported titanium catalysts which was developed in this laboratory. The influences of various conditions such as catalyst composition

temperature

triethylaluminum concentration

catalyst concentration

adding ester and H2 on the catalytic activity

decay of polymerization rate

inh value and isotactivity of resulting products were studied in detail. The structure and properties of poly (1-butene) were also studied by WAXD

DSC and 13C-NMR.It was found that TiCl4

Ti (OBu)4/MgCl2/ethylbenzoate (EB)/(C6H5)2SiCl2/AlEt3 catalyst had high catalytic activity

i.e. 3.2×104g.PB/g.Ti.h Isotacticity of ploducts was increased by adding P-CH3H6H4COOEt. i.e. I. I. %= 93.3.Molecular weight ofproducts was controlled by H2.The decay of polyme-rization rate with time fulfills the equation:Rt-Rs=(Ro-Rs)e-βt.
