Pulpal Response of Monkeys to Modifications of a Bisphenol A Composite Resin and Cement

open access: yes, 1972
This investigation demonstrated the minimal pulpal response of the teeth of monkeys to bisphenol A restorative materials in the form of a cement and as a composite resin.

Effect of Pal of filler particles on the physical properties of a dental composite

open access: yes, 1998
Use of silane treated fillers in chemical curing Bisphenol A-Glycidyl methacrylate (Bis-GMA) based dental composites has been found to improve the properties appreciably. The nature and concentration of the silane used is found to be critical in deciding

Cyclic-carbonate functionalized polymer brushes on polymeric microspheres: Immobilized laccase for degradation of endocrine disturbing compounds

open access: yes, 2018
A novel support material containing cyclic carbonate group for facile enzyme immobilization was synthesized from [poly(styrene-co-divinylbenzene)-graft-poly(glycidyl methacrylate)] "[PS-co-DVB-g-P (GMA)]" microsphere under carbon dioxide atmosphere.

UV-crosslinked glyoxal-methacrylate electrolytes for quasi-solid electric double layer capacitors [PDF]

open access: yes
In this paper, the difunctional oligomer bisphenol A ethoxylate dimethacrylate (BEMA), known for readily undergo UV-induced polymerisation, is employed to produce a highly crosslinked polymer network, in combination with poly(ethylene glycol) methyl ...

Composite-derived monomers affect cell viability and cytokine expression in human leukocytes stimulated with Porphyromonas gingivalis

open access: yesJournal of Applied Oral Science
Objectives: Dental composites release unreacted resin monomers into the oral environment, even after polymerization. Periodontal cells are, therefore, exposed to substances that potentially elicit the immune inflammatory response.

Preparation and characterization of a nanocellulose reinforced light-polymerized methacrylate-based dental adhesive [PDF]

open access: yes, 2019
The purpose of this research work was to develop a new dental adhesive, by inclusion of cellulose nanocrystals (CNCs) into a polymer matrix. CNCs were chosen as a component for dental adhesives due to its mechanical properties, dimensions, low density ...

Microplastics as Both a Sink and a Source of Bisphenol A in the Marine Environment

open access: yes, 2019
Microplastics were demonstrated to be an environmental sink for hydrophobic organic pollutants, while they can also serve as a potential source of such pollutants.

The thermal stability of cross-linked polymers: methyl methacrylate with divinylbenzene and styrene with dimethacrylates

open access: yes, 2001
Cross-linking of polymers is frequently presumed to enhance the thermal stability of polymer systems. Methyl methacrylate has been reacted with divinylbenzene and styrene with various dimethacrylates. These systems have been characterized by gel content,
