“…It has been shown that b-diketone can substitute the labile chlorine atoms through a C-alkylation reaction. 17 These compounds actually accelerate the degradation process owing to their mechanism of action and must be used with a good HCl acceptor. 14 Considering the excellent ability of Penzinc to absorb HCl, there would be a wonderful synergistic effect between Penzinc and b-diketone.…”

“…Minsker et al [118] and Michel et al [119] have investigated the stabilizing functionalities of 1,3-dicarbonyl compounds based on the example of the β-diketones. They found that one functionality of the β-diketones is as a substitute for labile chlorine atoms in the PVC chain (Formula 1.30).…”

“…It is suggested that b-diketones can substitute the labile chlorine atoms through a C-alkylation reaction to prevent the discoloration of PVC. And b-diketones can act as an acceptor or chelating agent for metal chloride by forming an inert complex to retard the sudden "zipper dehydrochlorination" of PVC [16,17]. Hitherto, study on the zinc barbiturate [Zn(H 2 L) 2 $2H 2 O, abbreviated as ZnL 2 )] as the thermal stabilizer for rigid PVC has not been reported, to the best of our knowledge.…”
