The aim of this study was to compare the bond strength between acrylic denture base and teeth subjected to 6 surface treatments. Ninety-six specimens were made with poly(methylmethacrylate) teeth bonded to a microwave-polymerized acrylic denture base material. The specimens were distributed into 6 groups (n=16) according to surface treatments: CT - no treatment (control); MN - methylmethacrylat...

Several innovative photopolymerizable siloxane-modified acrylic formulations were characterized, both in presence or absence of organically Boehmite (OMB) nanoparticles, in order to assess their rheological and kinetic behavior. The experimental formulations were mainly intended for the surface protection of porous stones or wood elements. The importance of the experimental investigation lies i...

The compositional dependence of the polymerization kinetics of multiacrylate copolymers with acrylic acid (AA) was examined. The multiacrylates considered were dior triacrylate esters of oligo(ethylene glycol) (OEG). The multiacrylate polymerization rate increased with the OEG chain length in the absence of added AA. This monomer size dependence was due to mobility-related effects on the pendan...

Defects of the eye may follow removal of a part of or the entire orbit. This results in the patient becoming visually, esthetically and psychologically handicapped. Restoring the defect with a silicone- or acrylic-based prosthesis not only restores esthetics but also gives back the lost confidence to the patient. This is a case report of a patient with a 'pthisical eye' and details the steps in...

Abstract Due to the shortage of high-quality natural sand, development polycarboxylic acid water reducer with excellent clay resistance has become a research hotspot in recent years. Using acrylic acid, methyl 4-vinylbenzoate, ethylene glycol monovinyl polyethylene ether molecular weight 3000 (EPEG-3000) as comonomers, under action sodium bisulfite formaldehyde-hydrogen peroxide redox initiator...

This study evaluated the influence of methacrylic acid (MA) incorporation on hardness, roughness, and flexural strength of a denture base acrylic resin. Thirty-two circular and 40 rectangular specimens were divided into four groups, according to the concentration of MA substituted into the monomer component of a heat-polymerized acrylic resin, as follows: 0% (Control), 10%, 20% and 50% (v/v). T...

We report the development and characterization of a polyacrylamide-based protein immobilization strategy for surface-bound protein assays, including concentration detection, binding affinity, and enzyme kinetics. Glutathione S-transferase (GST) fusion proteins have been labeled with an acrylic moiety and attached to acrylic-functionalized glass surfaces through copolymerization with acrylic mon...

The objective of this study was to determine the effect of simulated microwave disinfection on the tooth/acrylic resin impact strength. Acrylic molar teeth with a wax stick attached to the ridge lap were included in brass flasks. Specimens were made with Classico thermopolymerized acrylic resin, according to the groups: 1 and 5 - tooth with no treatment (control); 2 and 6 - tooth bur abrasion; ...

Dyes are a type of pollutant that have been discharged into water streams by various industries and had harmful effects on the environment human health. Therefore, present work was directed to recycle acrylic fibers waste be used as an adsorbent exclude dyes such methylene blue (MB) Congo red (CR) from dyes-polluted wastewater. Acrylic converted membrane followed chemical grafting with p-phenyl...
