The thermal stability of poly(sec-butyl methacrylate)
Termička stabilnost poli(sec-butil metakrilata)
Апстракт
The thermal stability of a series of poly(sec-butyl methacrylate)(PsBMA) samples was investigated by non-isothermal thermogravimetry (TG). The PsBMA samples were synthesised by bulk radical polymerization in the presence of various amounts of n-dodecyl mercaptan, an efficient chain transfer agent. By deconvoluting the differential TG (DTG) curves, the individual stages of the thermolysis of PsBMA were analyzed in detail: depolymerization, initiated by end-chain and random main chain scission, and desertification. The thermolysis activation energies of individual reactions were determined by the Flynn-Wall method. .
Ispitana je termička stabilnost serije uzoraka poli(sec-butil metakrilata) (PsBMA) neizotermnom termogravimetrijskom (TG) metodom. Uzorci PsBMA sintetizovani su radikalnom polimerizacijom u masi u prisustvu različitih količina n-dodecil merkaptana, efikasnog prenosioca aktivnosti lanca. Dekonvolucijom diferencijalnih TG (DTG) krivih uzoraka PsBMA detaljno su analizirane pojedine faze termolize PsBMA: depolimerizacija, inicirana β kidanjem i nasumičnim raskidanjem veze u osnovnom lancu, i deesterifikacija. Energije aktivacije reakcija termolize PsBMA određene su metodom Flynn-Wall-a. .
