The transport of methyl methacrylate monomer in poly(methyl methacrylate)
Journal of Applied Polymer Science, 1975The absorption kinetics and equlibria of methyl methacrylate monomer into poly(methyl methacrylate) were studied over a range of penetrant activities. The interval sorption kinetics at elevated activities were determined, compared, and contrasted with the integral sorption experiments in previously unpenetrated film samples.

Dendrimer/methyl methacrylate co-polymers: residual methyl methacrylate and degree of conversion
Journal of Biomaterials Science, Polymer Edition, 2005Dendrimer/methyl methacrylate co-polymers were studied for use in dental composites. The aim was to determine the effects of methyl methacrylate concentration in the resin mixture and polymerization method on the degree of conversion and residual monomer content of the copolymers.

Methyl Methacrylate Restrictions
JAMA: The Journal of the American Medical Association, 1974To the Editor.— I believe that a protest must be made regarding the position and actions taken by the Food and Drug Administration (FDA) in relationship to the use of methyl methacrylate. I think there is justification for the FDA to evaluate new and experimental drugs and to control these drugs in relationship to the toxicity and possible harm that ...

Methyl methacrylate in poly(methyl methacrylate)—validation of direct injection gas chromatography
Journal of Chromatography A, 2004Gas chromatography (GC) was investigated for the determination of residual methyl methacrylate (MMA) in heat-processed poly(methyl methacrylate) (PMMA) denture base material emphasizing recovery and validation. Standard solutions of MMA and emulsion-polymerized PMMA in dichloromethane were analysed, before and after distillation by a room-temperature ...

European Polymer Journal, 1977
Abstract The temperature dependence of chemical shifts in 1 H-NMR spectra of solutions of methyl methacrylate (MMA) in various solvents revealed specific interaction of MMA molecules with dimethylformamide (DMF). In the system MMA-poly (methyl methacrylate) (PMMA)-DMF, PMMA acts as a further component interacting with MMA.

Methyl methacrylate cranioplasty.
The Medical journal of Malaysia, 2005We conducted a prospective study in order to audit our experience of repairing cranial defects using Methyl methacrylate. This included a total of 49 patients undergoing cranioplasty using methyl methacrylate, of which 45 were males and 4 females. The age of patients at the time of surgery ranged from 16 to 40 years old, with an average of 24 years ...

Polarographic determination of methyl methacrylate
Talanta, 1967The permanganate oxidation of methyl methacrylate in weakly acidic solution yields methyl pyruvate. Hydroxylamine hydrochloride is used for destroying the excess of permanganate. At the same time it is consumed for oximation of the pyruvate, and the resulting oxime is determined polarographically. The reaction scheme of permanganate oxidation of methyl
