We evaluated the influence of monomer type, plasticizer content, and powder/liquid (P/L) ratio on setting characteristics light-cured acrylic permanent soft denture liners based poly(ethyl methacrylate/butyl methacrylate). Two monomers, iso-butyl methacrylate (i-BMA) 2-ethylhexyl (2-EHMA), that contained various concentrations acetyl tributyl citrate (ATBC) trace amounts photo initiator reducin...

Denture base resins are extensively used in dentistry for a variety of purposes. These materials can be classified as chemical, heat, light, and microwave polymerization materials depending upon the factor which starts the polymerization reaction. Their applications include use during denture base construction, relining existing dentures, and for fabrication of orthodontic removable appliances....

BACKGROUND Acrylic and bisacryl resins are widely used both during the temporization phase as well as for provisional restorations and the effect of external agents on dentin sensitivity can be reduced by the obliteration of the tubules. OBJECTIVE The purpose of this study was to evaluate diffusion of methyl methacrylate monomer through dentin by high performance liquid chromatography (HPLC) ...

A dendrimer amphiphilic polymer (A-D-HPAM) was synthesized by aqueous solution polymerization of acrylic acid (AA), acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic (AMPS), hydrophobic monomer cetyl dimethyl allyl ammonium chloride (DMCAAC-16), and skeleton GA1.0, using persulfate sodium bisulfite as initiators. The chemical structure A-D-HPAM was, respectively, analyzed Fourier transf...

Cellulose nanocrystals (CNCs) show promise for enhancing properties of waterborne latexes and coatings. Miniemulsion polymerization is a promising route to obtaining well-controlled latex distributions sufficient encapsulate CNCs in the monomer phase. Here, we demonstrate first miniemulsion resulting encapsulation that incorporates costabilizer, water soluble initiator, comonomer mixtures, aspe...

This work is devoted to the development and study of processes accelerated structuring polymer composite materials in field high-frequency current (microwave field) which are used electronic instrument-making industries, etc. The complex properties features epoxy, acrylic epoxy microwave investigated. In comparison with traditional method polymerization (convection heating), equally affects stu...

This work reveals the silyl ketene acetal (SKA)/B(C6F5)3 Lewis pair-catalyzed room-temperature group transfer polymerization (GTP) of polar acrylic monomers, including methyl linear methacrylate (MMA), and the biorenewable cyclic monomers γ-methyl-α-methylene-γ-butyrolactone (MMBL) and α-methylene-γ-butyrolactone (MBL) as well. The in situ NMR monitored reaction of SKA with B(C6F5)3 indicated t...

We report a new aqueous polymerization-induced self-assembly (PISA) formulation that enables the hydrophobic block to be prepared first when targeting diblock copolymer nano-objects. This counter-intuitive reverse sequence approach uses an ionic reversible addition–fragmentation chain transfer (RAFT) agent for RAFT dispersion polymerization of 2-hydroxypropyl methacrylate (HPMA) produce charge-...
