AB  - Poly(methyl methacrylate), PMMA, was prepared by reversible addition-fragmentation chain transfer, RAFT, polymerisation using 2-(2-cyanopropyl)-dithiobenzoate, CPDB, as the RAFT agent. The thermal stability of the resulting polymer approached that of anionically prepared PMMA, as determined by thermogravimetry. This was the consequence of the RAFT prepared polymer having no head-to-head links and no chain end double bonds, which are responsible for the relatively low thermal stability of radically prepared PMMA.
AB  - Poli(metil metakrilat), PMMA, je sintetisan kontrolisanom radikalnom RAFT polimerizacijom, odnosno reverzibilnom adiciono-fragmentacionom transfer polimerizacijom, u prisustvu 2-(2-cijanopropil)-ditiobenzoata, CPDB, kao RAFT agensa. Termička stabilnost PMMA sintetisanog RAFT polimerizacijom je slična polimeru dobijenom anjonskom polimerizacijom, što je pokazala termogravimetrijska analiza. PMMA sintetisan RAFT polimerizacijom pokazuje znatno bolju termičku stabilnost u odnosu na PMMA sintetisan polimerizacijom preko slobodnih radikala, zbog odsustva termički labilnih veza glava-glava ostataka monomera u polimernom lancu, kao i dvostrukih veza na krajevima lanaca.

AB  - The transfer constant to benzene in the radical polymerisation of di-n-butyl itaconate, DBI, was measured at 60 degrees C and found to have the value of 2.2 x 10(-3). This value is surprisingly high considering that benzene has no readily extractable hydrogen atoms and is usually considered to be a relatively inert solvent in radical polymerisations. The high values of transfer constants in the radical polymerisation of itaconates must be taken into consideration when planning the tailored polymerisation of these monomers.

AB  - The kinetics and mechanism of the thermal degradation of poly(diethyl fumarate) (PDEF) were studied by thermogravimetry, as well as by analysis of the thermolysis volatiles and polymer residue. The characteristic mass loss temperatures were determined, as were the overall thermal degradation activation energies of three PDEF samples of varying molar mass. Ethylene and ethanol were present in the thermolysis volatiles at degradation temperatures below 300 degrees C, while diethyl fumarate was also evidenced at higher degradation temperatures. The amount of monomer increased with increasing degradation temperature. The dependence of the molar mass of the residual polymer on the degradation time and temperature was established and the number of main-chain scissions per monomer unit, s/P-0, calculated. A thermal degradation mechanism including de-esterification and random main-chain scission is proposed. The thermal degradation of PDEF was compared to the thermolysis of poly(ethyl methacrylate) (PEMA), poly(diethyl itaconate) (PDEI) and poly(ethyl acrylate) (PEA).
