Abstract:

The course of styrene (S) polymerisation with the inclusion of SiC nanofibres (SiCNF) was compared with the course of reaction with singlewall carbon nanotubes (SWNT), whose radical activity has formerly been studied with respect to the polymerisation of another vinyl monomer – methyl methacrylate (MMA). The radical polymerisation of styrene in N,N-dimethylformamide (DMF) initiated by 4.4’-azobis(4-cyanopentanoic) acid (ACPA) at 333K in the presence of SiC nanofibres and SWNT was investigated by the dilatometric method. The principal difference in the chemical structure of the nanoparticles investigated is that the monomers influence their activity in the polymerisation. The SWNT act as loweffective inhibitors in the polymerisation of S and MMA but in an essentially different manner, whereas SiCNF have no impact on the process. The presence of carbonaceous nanoparticles in the processes investigated influences the thermal properties of polymerisation products differently.
