Photodegradation of Methacrylate/acrylate Copolymers
Although the effects of u.v. radiation on poly(methyl methacrylate) and poly(methyl acrylate) are superficially different, nevertheless there are obvious fundamental similarities and this copolymer system was chosen for study in order to observe the influence of one type of chain unit on the degradation reactions of the other. Rates of chain scission and crosslinking were measured at room tempe...
متن کاملIn Situ Photocrosslinking of Cinnamate Functionalized Poly(methyl Methacrylate-co-2-hydroxy Ethyl Acrylate) Fibers during Electrospinning
3.1 Chapter Summary A novel methodology for in situ crosslinking of polymeric fibers during electrospinning is described. The electrospinning apparatus was modified to facilitate UV irradiation of the electrospun fibers while in flight to the collector target. Three copolymers with different mol% of the photoreactive cinnamate functional group (4, 9 and 13 mol% respectively) were synthesized an...
متن کاملMethacrylate and Acrylate Allergy in Dental Students
A multitude of acrylic monomers is used in dentistry, and when dental personnel, patients or students of dental medicine become sensitized, it is of great importance to identify the dental acrylic preparations to which the sensitized individual can be exposed. Numerous studies confirm high incidence of sensitization to (meth) acrylates in dentatal professionals, as well as in patients undergoin...
متن کاملUltrastructural changes in human gingival fibroblasts after exposure to 2-hydroxy-ethyl methacrylate.
Polymerized resin-based materials are successfully utilized in medical applications. One draw- back is the release of monomers from the matrix due to an incomplete polymerization or degradation processes. Released monomers can diffuse in the systemic circulation and induceadverse effects to biological tissues. Although there are many hypotheses about the induction of cell death by resin monomer...
متن کاملPhysical Properties of Ethyl Methacrylate as a Bolus in Radiotherapy
Introduction Bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. The main property of various materials used presently as bolus is the water-equivalent electron density. Ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. The goal of this...
