Poly(methyl methacrylate)s with pendant calixpyrroles: polymeric extractants for halide anion salts.
Poly(methyl methacrylate)s containing pendant octamethylcalix[4]pyrrole subunits were prepared and demonstrated to be capable of extracting tetrabutylammonium chloride and fluoride salts from aqueous media.
Polymer-based composites were heralded in the 1960s as a new paradigm for materials. By dispersing strong, highly stiff fibres in a polymer matrix, high-performance lightweight composites could be developed and tailored to individual applications. Today we stand at a similar threshold in the realm of polymer nanocomposites with the promise of strong, durable, multifunctional materials with low ...
Miniemulsion homopolymerization reactions of methyl methacrylate (MMA) and styrene (STY) using poly(L-lactide) as co-stabilizer were carried out in order to prepare poly(L-lactide)/poly(methyl methacrylate) (PLLA/PMMA) and poly(L-lactide)/polystyrene (PLLA/PS) binary blend nanoparticles. The effect of PLLA concentration on methyl methacrylate (MMA) and styrene (STY) homopolymerization reactions...
Chitosan and poly(methyl methacrylate) (PMMA) composites were synthesized by polymerization with heating mechanochemical method. The obtained polymer analyzed the ATR FT-IR spectroscopy presence of intermolecular hydrogen bonds hydrophobic interactions in formation PMMA chitosan was shown.
conclusions the study results demonstrated that undergraduate prosthodontics students in their last two years of study had an average knowledge of working with methyl methacrylate. therefore, health education should focus more on working with dentistry substances, in order to enhance the knowledge level of the targeted students. results the mean level of individuals’ knowledge in regard to work...
Well-defined sterically stabilized diblock copolymer nanoparticles of 29 nm diameter are prepared by RAFT aqueous emulsion polymerization methyl methacrylate using a dithiobenzoate-capped poly(glycerol monomethacrylate) precursor. These evaluated as dispersant for the preparation organic crystalline microparticles via ball milling. This is exemplified azoxystrobin, which broad-spectrum fungicid...
