The polymerization was performed with phosphonium salt initiators (I(SbF6), I(PF6), I(AsF6) and I(BF4)) at ambient temperature to 200 degrees C for 1 h. The order of initiator activity was I(SbF6) &gt; I(PF6) &gt; I(AsF6) &gt; I(BF4). To examine the effect of the phosphine moiety on the initiator activity, polymerization was carried out with I(SbF6) (Ph(3)P) and II(SbF6) (Bu(3)P) at ambient temperature to 170 degrees C for 1 h. The order of reactivity was I(SbF6) &gt; II(SbF6). In general, the conversion percentage increased with increasing polymerization temperature. The thermal stability of these salts was measured by then-no gravimetric analysis (TGA). The solubility of phosphonium salts in various organic solvents and epoxy monomers was also investigated.</p>10aCationic polymerization10aglycidyl phenyl ether10aphosphonium salts10athermo-latent1 aGupta, Mukesh, Kumar1 aSingh, Raj, Pal  uhttps://library.ncl.res.in/content/thermally-induced-cationic-polymerization-glycidyl-phenyl-ether-using-novel-xanthenyl-0
