Abstract

Photochemical conversion of paramagnetic centres formed under γ-irradiation of polyacrylic acid (PAA) at 77 K has been studied. Middle macroradicals of PAA are involved in the photodissociation reaction to form hydroxyl radicals. They are also found to be capable of recombining. A scheme for the photoradical processes in PAA at 77 K is proposed.

聚丙烯酸中光自由基反应的机理和动力学

研究了聚丙烯酸(PAA)在77 K γ辐照下形成的顺磁中心的光化学转化。PAA的中间自由基参与光解反应形成羟基自由基。它们也被发现能够重组。提出了77 K下PAA光化过程的一种方案。
