A method to determine methylmethacrylate in air [PDF]
Acta Orthopaedica Scandinavica, 1988 To determine the air concentrations of methylmethacrylate monomer and thus obtain information about the safety in the operating theater, a methylmethacrylate Dräger tube was used in connection with a bellows pump. This method gives an instantly readable value correlated with more complicated gas chromatographic measurements.

Methylmethacrylate Hypersensitivity in Orthopaedic Surgery [PDF]
Acta Orthopaedica Scandinavica, 1978 The sensitivity to methylmethacrylate monomer in 25 patients undergoing orthopaedic surgery was studied. No relation could be found between the cardiovascular reactions observed during the cementation of the femoral prosthesis and the complement system, investigated by measuring the serum concentration of the haemolytic complement, components 3 and 4.

Effect of chain length on fragility and thermodynamic scaling of the local segmental dynamics in poly(methylmethacrylate) [PDF]
arXiv, 2007 Local segmental relaxation properties of poly(methylmethacrylate) (PMMA) of varying molecular weight are measured by dielectric spectroscopy, and analyzed in combination the equation of state obtained from PVT measurements. The usual variation of glass transition temperature and fragility with molecular weight are observed. We also find, in accord with
