Hardness of composite resin polymerized with different light-curing units
Introduction: The degree of polymerization depends on the type of light-curing unit. The aim of this study was to compare the hardness of composite resin cured by LED and Halogen light curing units. Methods: In this experimental study, 20 cylindrical samples of Tetric Ceram composite were prepared. Half of them were cured with Ultralume 2 LED and the other half with Astralis 7 Halogen light ...

متن کاملReactivity Studies of Maleimide Epoxy Resin with Long Chained Amines
After phenylmaleimido group was successfully incorporated into bisphenol-A type epoxy resins (B-13 ) to result in compound possessing both oxirane ring and maleimide reactive groups. The cured maleimide epoxy samples are obtained by thermally curing of the maleimide epoxy (MIE) compounds with aliphatic long chained amines such as Tetraethylenepentamine (TEPA), Bishexamethylenetriamine (BHMT), 2...
متن کامل[Polymerization reaction of heat curing type thermo-setting resin for crown and bridge].
The purpose of this paper is to investigate the chemical composition, the polymerization ability and the abrasion resistance of two brands (Isosit, Plastique) of thermo-setting resin for crown and bridge. 1. Isosit (Is) contained approximately 55 per cent of MFR type filler and 45 per cent of a comonomer (urethane dimethacrylate, 1, 3 butane dimethacrylate and 1, 10 decamethylene dimethacrylate...
متن کاملOligonucleotide cyclization: the thiol-maleimide reaction revisited.
A novel method to synthesize cyclic oligonucleotides (5- to 26-mer) using the thiol-maleimide reaction is described. The target molecules were obtained after subsequent removal of thiol and maleimide protecting groups from 5'-maleimido-3'-thiol-derivatized linear precursors. Retro-Diels-Alder conditions deprotecting the maleimide simultaneously promoted cyclization cleanly and in high yield.
