| 中文摘要 | the prediction, based on unsteady diffusion kinetics, of the enhancement of reactivity and incorporation of 1-hexadecene in its copolymerization with propylene on adding a small amount of ethylene (increase from 5,2 mol-% to 10,8 mol-% when 2% of ethylene was added, and to 16,1 mol-% when 5% was added) was verified in the terpolymerization of propylene/1-hexadecene/ethylene on a commercial solvay-type delta-ticl3 catalyst. the catalyst efficiency was thus also increased. these augmentations originate from the increase in diffusion coefficient of 1-hexadecene at the catalyst surface when the pp crystallinity decreases on introduction of ethylene. calculation based on unsteady diffusion kinetics showed that the order of diffusion coefficients ethylene > propylene > 1-hexadecene is reversed as the monomer concentration increases when the monomers are not at their equilibrium concentration. sequence distribution as determined by means of c-13 nmr revealed a tendency of blocky structure rather than a bernoullian one. the terpolymer compositions obtained by means of an ir method developed in this work conform rather well with the nmr results. results in this work not only support the unsteady diffusion kinetics but also provide a new route to prepare olefinic copolymer rubbers with heterogeneous titanium catalysts. |
