Kinetics of poly(alkylene terephthalate) formation catalyzed by metal ions

Kinetics of poly(alkylene terephthalate) formation catalyzed by metal ions. Rafler, Gerald; Dunger, Klaus; Reinisch, Gerhard (Inst. Polymerenchem., DAW, Teltow, E. Ger.Some commonly used reagents like 71-48-7 and 27043-73-8 are used in this experiment.). Faserforsch. Textiltech., 27(11), 579-84 (German) 1976. CODEN: FSTXA7. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) The kinetics of formation of [-O(CH2)nOCOC6H4CO-]m (n = 2 [25038-59-9], n = 6 [26637-42-3], n = 10 [27043-73-8]) by polymn. of p-C6H4[CO2(CH2)nOH]2 in the presence of metal catalysts [Mn(OAc)2 [638-38-0], Sb(OAc)3 [6923-52-0], Al(OAc)3 [139-12-8], Co(OAc)2 [71-48-7], GeO2] were detd. as a function of n. Differences in reactivity of hydroxyalkyl terephthalates can be explained by inductive effects. A mechanism for metal ion catalysis of polymn. is proposed, based on the dependence of kinetics and heat and entropy of activation on n. .
