用同步红外跟踪了St/HPMA自由基共聚合 ,发现在HTEMPO存在下可以发生活性自由基聚合 ,得到相对分子质量及其分布可控的PS -HPMA共聚物。
St-HPMA free-radical copolymerization was followed by synchronous infrared. It was found that living radical polymerization could occur in the presence of HTEMPO to obtain PS-HPMA copolymer with controlled molecular weight and its distribution.
