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 dynamic mechanical behavior of polymethyl methacrylate*)
Rheologica Acta, 1974In order to investigate the short time response of solid polymers, a high resolution laser interferometer has been employed to observe the detailed structure of stress waves produced by the impact of polymeric plates. From the observed stress waves the loading and unloading stress-strain paths followed by the material can be determined. For the polymer,

Polymethyl methacrylate microspheres in collagen
Seminars in Cutaneous Medicine and Surgery, 2004Artecoll was developed about 20 years ago and underwent a number of production changes until it recently became FDA approved under the new name of Artefill. This product contains 20% polymethyl methacrylate (PMMA) microspheres with a diameter of 30 to 40 microm, which are suspended in a 3.5% atelo-collagen solution.

Fabrication of a capillary immunosensor in polymethyl methacrylate
Biosensors and Bioelectronics, 2002A method for fabricating capillary-based immunosensors in a coupon milled from an inexpensive, commodity plastic (PMMA, plexiglass) is demonstrated. The key feature of the technique is the use of sol-gel technology to deposit a glass-like (Si [bond] OH) film on surfaces of the plastic capillary channels to facilitate antibody immobilization.

Cranioplasty using polymethyl methacrylate prostheses
Journal of Clinical Neuroscience, 2009In this retrospective study we attempted to assess the clinical performance of prefabricated polymethyl methacrylate (PMMA) prostheses and to determine whether they outperform intra-operatively moulded PMMA prostheses in reducing operating time, blood loss and surgical complications in elective delayed cranioplasty operations, after decompressive ...

Cyclic Viscoelasticity of Polymethyl Methacrylate
Inorganic MaterialsThe results of a study of the creep of polymethyl methacrylate (PMMA) under cyclic loading are presented. The viscoelastic behavior of PMMA was analyzed under normal operating conditions, before the onset of material damage processes. Creep during continuous deformation is a superposition of two processes: the creep acceleration due to a stress ...

Fracture Markings in Polymethyl Methacrylate
Nature, 1958THE surface markings on the fracture surfaces of glass and plastics show that the fracture is discontinuous and that patterns are formed through secondary initiations ahead of the main fracture front which unite to form the completed fracture surface1–3.
