Thermoforming polymethyl methacrylate
The Journal of Prosthetic Dentistry, 1995This study characterized a range of commercially available polymethyl methacrylate sheets with respect to molecular weight, residual monomer content, and glass transition temperature and then developed a thermoforming procedure that produced visually satisfactory thermoformed polymethyl methacrylate specimens.

The compounds disclosed herein are acetylenic methacrylates having the formula\u000a\u000aCH2 = C(CH3)COO-Z-C=CH\u000a\u000awherein Z represents a divalent hydrocarbon radical having at least 2 carbon atoms. Because of their terminal acetylenic radical these compounds are very reactive and capable of producing various acetylenic derivatives.

Molecular Mobility in Poly(butyl methacrylate) and Poly(methyl methacrylate)
Molecular Simulation, 2004Molecular mobility is studied in poly(butyl methacrylate) and poly(methyl methacrylate) (PMMA) with molecular dynamics simulations in order to understand the effect of the α–β crossover on the β relaxation activation energy and co-operativity. In the high frequency range investigated, the estimated β process activation energy is decreased as compared ...

Some aspects of the copolymerization of glyceryl methacrylate with methyl methacrylate
Polymer, 1995Abstract Free radical polymerization of glyceryl methacrylate (GMA) has been conducted (i) in bulk, (ii) in moderately concentrated aqueous solution and (iii) in dilute aqueous solution. For (i) and (ii) the resultant poly(glyceryl methacrylate) (PGMA) was either insoluble or only swelled in a wide range of common solvents, whereas for (iii ...

Polyurethane or Methacrylate For Arthroplasty
JAMA: The Journal of the American Medical Association, 1972To the Editor.— I have just read, with considerable interest and dismay, Dr. Mandarino's reply (219:512, 1972) to Dr. Eftekhar's article on low-friction arthroplasty (218:705, 1971). Dr. Mandarino suggests, if I interpret his remarks properly, that we reconsider the use of polyurethane foam (Ostamer) as a substitute for methylmethacrylate as the ...

Problems in methacrylate embedding
1960Although certain epoxy resins have been demonstrated to be excellent embedding media for many materials, electron microscopists will continue, no doupt, to use methacrylate, for many purposes. If properly handled methacrylate is an excellent embedding medium and has the advantage of rapid penetration and consequently a much shorter delay before ...
