Development of reactive methacrylates based on glycidyl methacrylate

Journal of Polymer Science Part A: Polymer Chemistry, 2010
AbstractSix methacrylate monomers have been synthesized for use as reactive diluents in dental composites and evaluated to investigate the relationship between molecular structure and monomer reactivity. Four were synthesized by reactions of glycidyl methacrylate (GMA) with various acids, 2‐(2‐methoxyethoxy)acetic acid (1), 2‐(2‐(2‐methoxyethoxy)ethoxy)

Porous glycidyl methacrylate-bentonite composite

Russian Journal of Physical Chemistry A, 2011
Crosslinked macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate (CP) and copolymer composite with acid modified clay (CP-SA) were prepared by radical suspension copolymerization and functionalized by ring-opening reaction of the pendant epoxy groups with diethylene triamine (CP-deta and CP-SA-deta).

Ionic transport through bis‐glycidyl methacrylate films

Journal of Oral Rehabilitation, 1980
SummarySpecific ion meter studies have shown that ionic transport through bis‐GMA fissure sealant films is selective and that dissolved fluoride ions disappear from the solution around tooth sections at a more rapid rate than do calcium and chloride ions.

The thermal degradation of glycidyl methacrylate-methyl methacrylate copolymers

Polymer Degradation and Stability, 1996
Abstract Copolymers of glycidyl methacrylate and methyl methacrylate with widely differing compositions have been studied by thermal volatilisation analysis (TVA), thermogravimetry (TG), differential thermal analysis (DTA) and pyrolysis-mass spectrometry (Py-MS) techniques. The apparent activation energies for the decomposition of the copolymers were

Thermal degradation of poly(glycidyl methacrylate)

Polymer Degradation and Stability, 1990
Abstract The degradation behaviour of poly(glycidyl methacrylate) (PGMA) has been studied using thermogravimetry in dynamic nitrogen and thermal volatilisation analysis (TVA) under vacuum, with programmed heating at 10°C/min. Volatile products have been separated by subambient TVA and identified.

Grafting of glycidyl methacrylate onto gelatin

Journal of Applied Polymer Science, 1991
AbstractGelatin was graft copolymerized with poly(glycidyl methacrylate) using potassium peroxydisulfate in aqueous medium. Effect of temperature, time, initiator, monomer, and backbone concentrations were studied. The percent grafting was found to increase initially and then decrease in all the cases except with variation of monomer concentration. The

Synthesis of glycidyl amine adducts and their copolymerization with glycidyl methacrylate

Journal of Applied Polymer Science, 2005
AbstractSyntheses of new adducts from glycidyl methacrylate and the following amines: aniline, p‐phenylenediamine, 4,4′‐oxydianiline, 4,4′‐diaminodiphenylmethane, 4,4′‐diaminodiphenyl sulfone, 4,4′‐thiodianiline, and 4,4′‐diaminodicyclohexylmethane, are presented. These adducts were copolymerized with glycidyl methacrylate.

Immobilization of Enzymes on 2‐Hydroxyethyl Methacrylate and Glycidyl Methacrylate Copolymer Brushes

Chemistry – An Asian Journal, 2014
AbstractThe immobilization of enzymes is of paramount importance to maintain their activity and stability. In this study, surface‐initiated atom‐transfer radical polymerization was applied to prepare poly(2‐hydroxyethyl methacrylate)‐block‐poly(2‐hydroxyethyl methacrylate‐co‐glycidyl methacrylate) brushes on glass slides.

Atom transfer radical copolymerization of glycidyl methacrylate and methyl methacrylate

Journal of Applied Polymer Science, 2011
AbstractGlycidyl methacrylate (GMA) and methyl methacrylate (MMA) copolymers were synthesized by atom transfer radical polymerization (ATRP). The effect of different molar fractions of GMA, ranging from 0.28 to 1.0, on the polymer polydispersity index (weight‐average molecular weight/number‐average molecular weight) as the indicator of a controlled ...

Preparation of methyl methacrylate and glycidyl methacrylate copolymerized nonporous particles

Journal of Polymer Science Part A: Polymer Chemistry, 1999
Particles of methyl methacrylate (MMA) and glycidyl methacrylate (GMA) copolymer having narrow size distributions were prepared by the method of dispersion polymerization. Results from the analysis of particle porosity and the correlation of specific surface area with the reciprocal of particle diameter suggest that the prepared particles were ...
