Light-curing polyethyl methacrylate (PEMA)-urethane dimethacrylate (UDMA) resins and polymethyl methacrylate (PMMA)-UDMA resins were prepared by two processes. For first step, PEMA or PMMA powders wer...
The effect of new adhesives on the bond strength of elastomeric impression materials to acrylic trays was evaluated. Two polyvinyl siloxane impression materials (Fusion and Imprinsis) with reactive ad...
Three-armed poly(methyl methacrylate)[PMMA] was synthesized by atom transfer radical polymerization at 100 °C using benzene-1,3,5-triyl tris(4-(bromomethyl) benzoate as 3-armed initiator and a cuprous...
A series of supported intermetallic Pb-Pb catalysts were prepared with the impregnation method by changing the support (silica, molecular sieve or g-alumina ) and the pore size. The chemical states of...
Methyl methacrylate (MMA) is a monomer that is polymerized into resin by light and heat, producing a clear, resistant, durable and relatively inert plastic material. Because of these characteristics, ...
The aim of this study was to examine the mechanical properties of a new surface-modified denture resin for its suitability as denture base material. This experimental resin is made by copolymerization...
Electrospinning is a versatile method of preparing polymer nanocmposite fibers. Electrospun nanocomposite fibers of poly(methyl methacrylate) and single walled carbon nanotubes were prepared. The fibe...
The elution curves of caffeine, vanillin, coumarin, and methyl paraben, which have different hydrophobicities, in a bed packed with porous methyl methacrylate resin, were measured by the pulse respons...
Free radical photopolymerization of methyl methacrylate (MMA) initiated by 2-mercaptothioxanthone (TX-SH), thioxanthone-thioacetic acid (TXSCH2COOH), and thioxanthone-carboxymethoxy acetic acid (TXOCH...
Questions over the usefulness of a self-etching primer with resin adhesive in the bonding of orthodontic brackets remain unsolved. The purpose of this study was to determine the effects of using M...
Objective: To produce an antibacterial adhesive for orthodontic bonding without compromising the mechanical property.Materials and Methods: We added benzalkonium chloride (BAC) to the Superbond C&B (4...
摘要 以N-氯代丁二酰亚胺(NCS)为引发剂,分别与CuCl/PMDETA (N, N,N’, N’, N’’ -pentamethyldiethylenetriamine), CuCl/MA5-DETA(N, N, N’, N’, N’’ -penta (methyl acrylate) diethylenetriamine),CuCl/bipy (2,2’-bipyridyl)催化体系进行了甲...
期刊信息 篇名 Photosensitivity and grating development in trans-4-stilbenemethanol-doped poly (methyl methacrylate) materials 语种 中文 撰写或编译 撰写 作者 Jianming Yu,Xiaoming Tao,Hawywa Tam,Dongxiao Yang,and M. Suley...
Poly (methyl methacrylate) -- PMMA -- and poly (methacryloyl chloride) -- PMACl -- were synthesized by free radical solution polymerization. The thermal stabilities of these polymers were determined w...
Oxidative dehydrogenation of methyl isobutyrate (MIA) mainly to methyl methacrylate (MMA) and methacrylic acid (MA) over an industrial oxidation catalyst designed for oxidation of isobutene to methac...
