PHOTOSENSITIZED DEGRADATION OF POLYISOPRENE SOLUTION BY USING DICYANOANTHRACENE AS SENSITIZER
以二氰蒽为敏化剂的聚异戊二烯敏化光降解

In this paper, the photodegradation of polyisoprene (PIP) with 9,10-dicyanoanthrace ne (DCA) as a photosensitizer has been studied. In the photodegradation process, it was found that the reaction proceeds according to the singlet oxygen mechanism. The DABCO-singlet oxygen quencher was used to quench 1O2. It was found that in the quenching process, the electron transfer between DABCO and DCA occured and the photostabilization of DABCO in the DCA-PIP system was promoted.
