2
The molecular weight distribution of the product provided by the present invention is narrower than the product provided by the masspolymerization.
本发明所得产品的分子 量分布较本体聚合所得者狭窄。
3
The effects of initiators and thermal initiation on a reaction rate, molecular weight and molecular weight distribution of products in a masspolymerization of styrene were investigated.
