Book excerpt: "A study has been made of the thermal degradation of poly (methyl methacrylate) of different molecular weights in toluene, ethyl acetate and chloroform. Four poly (methyl methacrylate) samples having molecular weights of 2,210,000, 733,000, 320,000, and 43,00, respectively were studied in this investigation. The results indicated that the polymer having a molecular weight of 2,210,000 undergoes degradation while the low molecular weight polymers having molecular weights of 733,000, 320,000, 43,000 undergo reverse polymerization"--Abstract, leaf [ii].

Book excerpt: "A study has been made of the thermal degradation of poly (methyl methacrylate) of two different molecular weights, 2,303,000 and 43,000, in 1,2-dichloroethane in a closed system. The results indicated that the polymer having a molecular weight of 2,303,000 undergoes degradation while the low molecular weight polymer 43,000 undergoes reverse polymerization, and the molecular weight remains constant. The molecular weight of high molecular weight samples after 48 hours decreased from 2,303,000 to 2,232,000 and 1,690,400 at 50°C and at 98.5°C, respectively"--Abstract, leaf [i].

This book was released on 1995 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal degradation of poly([alpha]-methylstyrene) in solution was investigated at various temperatures (150-225 C) and polymer concentrations (2.00-20.0 g/L) at 6.8 MPa (1000 psig). The molecular weight distributions (MWDs) of the reacted polymer at these conditions were examined at four different residence times. Experimental data indicated that the polymer degraded to its monomer, [alpha]-methylstyrene. No other degradation products were observed. Continuous-mixture kinetics was used to examine the MWDs and to obtain the rate coefficient for degradation and its activation energy. The rate was first-order in polymer concentration with a rate constant at 225 C of 0.01 min{sup - 1} and an activation energy of 66.5 kJ/mol (16.0 kcal/mol). The maximum conversion observed at 275 C was 1.2%. Hydrogen-donor solvent, tetralin, had no effect on the degradation.

Available in PDF, EPUB and Kindle. Book excerpt: Polyvinylbenzene and copolymers of styrene with divinylbenzene and with trivinylbenzene were pyrolyzed in a vacuum in the temperature range 240 degrees to 450 degrees C. The results indicate a gradual increase in thermal stability of the copolymers as the amount of crosslinking agents divinylbenzene and trivinylbenzene is increased. Thermal degradation studies of polystyrene, polymethylene, polytetrafluoroethylene, poly-alpha-methylstyrene, polypropylene, polyisobutylene and PMMA showed that the higher the temperature and pressure of pyrolysis the greater is the fragmentation of the degradation products. Instrumentation for the study of the thermal degradation of organic polymers was also investigated.
