Polymersomes are exciting self-assembled structures with great potential in pharmaceutical applications. A systematic investigation of a novel series methacrylate-based polymersomes is reported this study. Five well-defined ABA triblock copolymers being based on tri(ethylene glycol) methyl methacrylate and B 2-(diethylamino)ethyl (DMAEMA) were synthesized using living polymerization method. The...

The ultrasonic velocity, density and viscosity at 318K have been measured in the binary systems of Methyl methacrylate + Toluene and Methyl methacrylate + Dimethylacetamide. In this work an attempt has been made for the first time to investigate the behavior of binary solutions of Methylmethacrylate(MMA) in Toluene and Dimethylacetamide(DMAC) with regard to acoustical parameters such as adiabat...

th dentistry. Early 20 century sawintroduction of various newer materials like stainless steel, cobalt chromium alloys, acrylic resins(heat cure and self-cure) as DB materials.However, acrylic resin seems to be a material, which got more attention because it fulfils many of the desired properties like ease of processing, favourable working characteristics, accurate fit, stability in oral enviro...

Without intervention, it has been found that surface-initiated photoiniferter-mediated photopolymerization (SI-PMP) of methyl methacrylate suffers from irreversible termination, which leads to cessation of polymerization. These irreversible termination reactions were successfully reduced by preaddition of tetraethylthiuram disulfide (TED). The poly(methyl methacrylate) layers were also reinitia...

Quaternary ammonium methacryloxy silicate (QAMS), an organically modified silicate (ORMOSIL) functionalized with polymerizable methacrylate groups and an antimicrobial agent with a long lipophilic alkyl chain quaternary ammonium group, was synthesized through a silane-based sol-gel route. By dissolving QAMS in methyl methacrylate monomer, this ORMOSIL molecule was incorporated into an auto-poly...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013200520 DESCRIPTION Derivatives of methacrylic acid showing strong sensitising properties are frequent causes of allergic contact dermatitis in dentists and dental technicians. Methyl methacrylate is used for fabrication of acrylic removable partial or complete ...

Cranioplasty is not only performed for cosmetic reasons but also for physiological requirements to balance the cerebral hemodynamics and to protect the brain from external traumas. Methyl methacrylate is one of the most preferred materials for cranioplasty. It is usually prepared out of the surgical site and therefore modelling of the cranioplasty material to fit the bone defect is sometimes di...

Structurally robust block copolymer templates with feature sizes of approximately 10 nm were prepared from functionalized poly(methyl methacrylate)-b-polystyrene block copolymers. By the inclusion of benzocyclobutene crosslinking groups in the polystyrene block, the covalent stabilization of thin films to both thermal treatment and solvent exposure became possible. In addition, the crosslinking...

Our previous studies demonstrated great potential of methyl methacrylate and vinylbenzyl chloride based copolymer electrolytes for alkaline fuel cell applications. In this study, a number of factors including polymer composition drift, molecular weight, and polymer crosslinking is investigated to understand their effects and to precisely control the electrolyte properties including conductivity...

Polymer optical fiber (POF) with a highly photosensitive poly(methyl methacrylate-co-methyl vinyl ketone-co-benzyl methacrylate) core is fabricated. Gratings can be fabricated in the core of a POF with a low-cost mercury lamp. The part of the emission spectrum of the mercury lamp in which the cladding material exhibits photosensitivity is effectively filtered by a 1.5-mm-thick Pyrex glass to en...
