AB  - U okviru ovog rada prikazani su rezultati dobijeni izučavanjem uticaja molarne mase (generacije), broja krajnjih grupa, kao i vrste krajnjih grupa na termičku stabilnost alifatskih hiperrazgranatih poliestara (AHP). Vrsta krajnjih grupa je menjana modifikovanjem sintetizovanih hiperrazgranatih poliestara sa hloridom propionske kiseline i stearinskom kiselinom. Termička stabilnost ispitivanih uzoraka je određivana merenjem promene mase uzorka sa temperaturom pomoću instrumenta NETZSCH TG 209 u atmosferi azota pri brzini zagrevanja od 10 oC. Poređenjem temperatura pri gubitku mase od 5, 20 i 40 mas.% za ispitivane nemodifikovane uzorke AHP, očitanih sa termogravimetrijskih krivih, konstantovano je da njihova termička stabilnost blago raste do četvrte generacije, a zatim ostaje praktično konstantna. Modifikovanjem krajnjih hidroksilnih grupa uzoraka AHP druge, treće i četvrte generacije sa propionskom i stearinskom kiselinom termička stabilnost uzoraka se blago povećava.
AB  - The influence of the molar mass (generation), number and type of end groups on the thermal stability of aliphatic hyperbranched polyesters are presented in this study. Different end groups were obtained by modification of the samples with chlorides of propionic acid and stearic acid. The thermal stability of the hyperbranched polyesters was determined by thermogravimetry using a NET-ZSCH TG 209 instrument in nitrogen atmosphere at a heating rate of 10°C/min. A comparison of the temperatures obtained for mass losses of 5 20 and 40 wt% for unmodified samples showed that the thermal stability increased up to the fourth generation and then remained practically constant. An increase in the thermal stability of modified samples of the second, third and fourth generation was observed.
