The thermal degradation of poly(methyl methacrylate) (PMMA) in the presence of polysulfide polymers, namely, poly(styrene disulfide) (PSD) and poly(styrene tetrasulfide) (PST) was studied using thermogravimetry (TG) and direct pyrolysis‐mass spectrometric (DP‐MS) analysis. Both PSD and PST were found to stabilize the PMMA degradation, which was explained by both radical recombination and a chain‐transfer mechanism. © 1997 John Wiley & Sons, Inc.
