POLYMERISATION OF METHYL METHACRYLATEDENIS G. M. WOODPERCY A. SMALL
The kinetics of multi-site phase transfer catalysed (MPTC) radical polymerisation of methyl methacrylate (MMA) using potassium peroxydisulphate (PDS) and synthesised 1, 4-Bis (tributyl methyl ammonium) benzene dichloride (TBMABDC) as multi-site phase transfer catalyst was investigated in cyclohexane...

The total surface area of the polymer particles was often less than the saturation area for the emulsifier. Large increases in particle size, such as occur in the continuous emulsion polymerisation of styrene, were not observed in the continuous emulsion polymerisation of methylmethacrylate. The ...

Anionic polymerization of methylmethacrylate, initiated by fluorenyl-alkali metals in amine media, gives syndiotactic polymers. With amines having high dielectric constant (NH 3 and MeA) Li +, Na + and K + give approximately the same values of differential enthalpies and entropies of activation ...
Magnetic resonance imaging has been used to spatially map the time course of the bulk polymerisation of methylmethacrylate. Both two-dimensional projection and slice-selective techniques have been employed. Image intensities give qualitative information about viscosity, reaction rates and the localised ...
On September 6th, 1994, Mitsuo Sawamoto and three co-authors from Kyoto University submitted to the journal ‘Macromolecules’ a paper with the catchy title “Polymerisation of Methyl Methacrylate with the Carbon Tetrachloride/Dichlorotris- (triphenylphosphine)ruthenium(II)/Methylaluminum Bis(2,6-di-te...
recycling technologies.For acrylic solutions, manufacturers have introduced recycling methods through avenues of mechanical and chemical recycling, which enables them to collect pre- and post-consumer PMMA waste and convert it into the recycled methyl methacrylate (rMMA) monomer, the polymer’s ...
