摘要：

Using experimental results obtained by hot-stage light microscopy, the sintering behaviour of off-reactor spherical grades of polypropylene and poly(methyl methacrylate) were considered. Sintering rates were found to be strongly influenced by initial particle size, melt temperature and viscosity and could be modelled using the Frenkel equation. Examination of the microstructure between sintered polypropylene particles revealed a distinct transcrystalline zone, which was relatively insensitive to sintering temperature and cooling rate.
