The number-averagemolecularweight and molecular weight distribution of the polymer were not sensitive to temperature.
温度升高， 聚合反应的转化率增加， 但产物的数均分子量及分子量分布无明显变化；
2
The number-averagemolecularweight of the polymer decreased, the molecular weight distribution was slightly wide, but the conversion increased as the polymerization temperature increasing.
温度升高，聚合反应的转化率增加，聚合产物数均分子量降低；
