The thermal stability of poly(sec-butyl methacrylate)

, 2000
The thermal stability of a series of poly(sec-butyl methacrylate)(PsBMA) samples was investigated by non-isothermal thermogravimetry (TG). The PsBMA samples were synthesised by bulk radical polymerization in the presence of various amounts of n-dodecyl mercaptan, an efficient chain transfer agent.
