| 摘 要： | 本工作利用样品１３－ＮＭＲ波谱的全部数据，把它们分成六组，考虑丙烯反插的情况，建立三元共聚合模型计算了各类催化体系得到的乙烯丙烯共聚物的序列分布，动力学参数．结果和实测值吻合得很好．该计算模型既适用于反插丙烯存在的情况也适用于反插丙烯不存在的情况，对于分辨率较差的谱图也可直接从组峰面积进行计算，既避开了分峰的困难，也避免了勉强分峰带来的误差，可得到良好的结果

| Abstract: | y utiliaing all speCtra data and dividing them into six groups, in the presence of inverted propylene, a ternary copolymerizaholl model was established to calculate the sequence distribuhon of copolymers prepared with different catalyst systems. The results agree with observed values very well. This model is applicableto case both having and not having inverted propylene in chain. This method notonly can be utilind in calculating the area of peaks and kinetic parameters r1, r2but also can avoid the difficulties of separating peaks and the ermrs caused byseparating peaks reluctulltly. |
