In this paper, three modified tetraethyl orthosilicate surface treatment agents were prepared by using (TEOS) as the preparation monomer, isobutyltriethoxysilane (IBTS) hybridizer, and acrylic acid, phosphoric hydrochloric acid catalysts. The effects of on permeability airport pavement concrete investigated water absorption tests, contact angle penetration resistance chloride ion carbonation me...

Plastic embedding preserves tissue structure much more faithfully than does paraffin. Acrylic polymerization is innocuous to dye-binding groups in sections. The water solubility of glycol methacrylate monomer and the hydrophilic properties of the polymer allow for convenience in dehydration and for versatility in staining sections. Five years of experience with glycol methacrylate (GMA) embeddi...

Synthesized graft copolymers of chloroprene rubber with acrylic acid. A mixture benzene and dimethylformamide was used as a solvent, potassium persulfate polymerization initiator. Based on the dependence copolymerization rate concentrations components temperature, order reaction in terms concentration acid (2.0), (1.2) activation energy process (24.4 kJ/mole) were determined. The degree graftin...

Polymethylmethacrylate is clinically used as a bone cement in various orthopedic and trauma surgeries. Post the surgery, such conventional acrylic has been reported to cause adjacent vertebral fractures; modifying it by adding linoleic acid formulation shown potential averting fractures thanks bone-compliant mechanical properties, besides providing convenient handling properties. Although resul...

This work reports the preparation and characterization of poly(styrene-acrylic acid) (St/AA) submicrocapsules by using the miniemulsion copolymerization method. AA was introduced to miniemulsion polymerization of St to increase the zeta potential and the resulting electrostatic stability of St/AA submicrocapsules. Phytoncide oil was adopted as the core model material. Miniemulsion copolymerizat...

In this work, two bio-based raw materials, rapeseed oil and technical-grade oleic acid, were modified to yield acrylated monomers. Polymeric latexes designed for coating applications synthesized using emulsion polymerization. Methyl methacrylate butyl acrylate copolymerized with various ratios of the monomers (0–20 wt.% in monomer mixture). The polymerization high conversion low coagulum conten...

As a functional decorative material on the surface of printing and packaging, coating plays role increasing gloss, wear resistance, antifouling. It has broad application prospects in high-end printed materials such as posters, art reproductions, maps. In this paper, dodecafluoroheptyl methacrylate was used fluorine-containing monomer, which to modify epoxy resin introduce fluoride first. Under ...

Bioadhesive polymeric hydrogels capable of firm adhesion to various biological tissues have acquired considerable attention due their significance in medicine and dentistry. Thus far many types bioadhesive been investigated using different polymers such as polyacrylates, poly(ethylene glycol)s, the derivatives polysaccharides proteins, while less has paid polyamphoteric properties cross-linked ...

Denture stomatitis is a very common disease affecting the oral mucosa of denture wearers. The aim of this study was to measure the antifungal effect of henna against Candida albicans adhered to acrylic resin as a possible method for prevention of denture stomatitis. One-hundred-eighty acrylic plates were prepared of heat-cured acrylic denture resin. The specimens were divided into six groups of...
