Abstract

"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 50⁰C and at 98.5⁰C, respectively"--Abstract, page [i].
