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.

Heterobimetallic Janus Catalysts for the One‐Pot Synthesis of Polar‐Apolar Block Copolymers
Angewandte Chemie, EarlyView.Heterobimetallic Janus catalysts act as bifunctional initiators, combining two distinct polymerisation mechanisms in one pot to deliver well‐defined apolar‐polar block copolymers. Combining Earth abundant Ti and Al catalysts for respective α‐olefin and lactone polymerisation, the orthogonal activity is enabled by unprecedented initiation from a Ti ...

Cardiovascular Effects of Methylmethacrylate Cement [PDF]
BMJ, 1972 Experiments were carried out on dogs in an attempt to identify the mechanisms underlying the systemic hypotension associated with the application of acrylic cement substances to raw bone surfaces, as in reconstructive hip surgery. Intravenous injection of the liquid component of such cements (monomeric methylmethacrylate) into six dogs produced a ...
