摘要

Influences of lanthanum stearate (LaSt3) and calcium stearate/zinc stearate (Ca/Zn) stabilizers on stabilization efficiency of dibutyltin dilaurate (DBTDL) to polyvinyl chloride (PVC) in air were investigated. The results revealed that the stabilization effect of DBTDL could be achieved by the La/Sn stabilizers with a ratio of 8/2. Addition of DBTDL could enhance thermal property and reduce dynamic storage modulus (G’) at 180oC for PVC containing LaSt3 or Ca/Zn stabilizers. On the other hand

incorporation of LaSt3 did not influence the stabilization efficiency of DBTDL markedly; while addition of Ca/Zn stabilizers could significantly decrease thermal property for the DBTDL stabilized PVC. Furthermore

the effects of LaSt3 and Ca/Zn stabilizers on the stabilization efficiency of DBTDL were explained in the framework of ionization potential.
