Thermal degradation of PMMA in fluidised beds.
K Smolders,Jan Baeyens +1 more
TL;DR: It was demonstrated that the heat transfer in the fluid bed could be estimated by the equation of Kothari and a design procedure for a fluid bed PMMA-depolymerisation reactor is outlined and illustrated for a process of 1 tpd PMMA.

Pyrolysis-gas-liquid-chromatography utilised for a kinetic study of the mechanisms of initiation and termination in the thermal degradation of polystyrene
TL;DR: In this paper, the pyrolysis mechanism involves both initiation at the chain-ends and initiation by random scission, and the activation energies for scission and end-initiation for both types of sample were analyzed.

The termination reaction in radical polymerizations. Polymerizations of methyl methacrylate and styrene at 25
TL;DR: In this paper, the number of initiator fragments per polymer molecule was determined by measurements of the average molecular weights of the polymers by osmometry and the specific activities of polymers and the initiator by gas counting.

The termination reaction in radical polymerizations. II. Polymerizations of styrene at 60° and of methyl methacrylate at 0 and 60°, and the copolymerization of these monomers at 60°
TL;DR: In this paper, the copolymerization of styrene and methyl methacrylate at 60° and 0 and 60° using 2,2′-azo-bis-isobutyronitrile labeled with C14 as initiator has been investigated.

Direct examination of polymer degradation by gas chromatography: I. Applications to polymer analysis and characterization
TL;DR: Two techniques of polymer degradation have independently been incorporated into a conventional gas chromatography apparatus, so arranged that the carrier gas sweeps the degradation products directly into the analysis column as mentioned in this paper, since any temperature up to 1000°C may be selected for the degradation.
