合成了一种含有伯叔过氧基的新型过氧化物单体N-[（叔丁基过氧基）甲基]丙烯酰胺（tBPMAAm），并将其与甲基丙烯酸辛酯（OMA）进行自由基共聚，得到了一种新型功能性聚过氧化物（FPP）。分析共聚动力学以找到tBPMAAm和OMA单体竞聚率（r1，r2）和Q − e值。动力学特性提供了一种方法来控制FPP的组成和其在自由基过程中的反应性。预期所开发的含有长烷基片段的官能化聚过氧化物提供对聚合物表面的亲和力。同时，由于过氧化物基团在高温下容易分解，因此FPP可用作自由基聚合的大分子引发剂。因此，我们预计，在未来的FPP将作为一个有效的聚合物表面改性剂。
N-[(tert-Butylperoxy)methyl]acrylamide (tBPMAAm), a new peroxide monomer containing a primary-tertiary peroxide group, was synthesized and employed for radical copolymerization with octyl methacrylate (OMA) to yield a novel functional polyperoxide (FPP). Copolymerization kinetics were analyzed to find tBPMAAm and OMA monomer reactivity ratios (r1, r2) and Q − e values. Kinetic characteristics provide a way to control FPP composition and its reactivity in radical processes. It is expected that the developed functional polyperoxide containing long alkyl fragments provides an affinity to polymeric surface. At the same time, since the peroxide groups readily decompose at elevated temperatures, the FPP can be used as a macroinitiator of radical polymerization. As a result, we expect that in the future the FPP will be applied as an efficient modifier of the polymeric surface.
