Reactions of glycidyl methacrylate with the crown and chair conformers of tetra(4-hydroxyphenyl)calix[4]resorcinarene were studied. The reactions were done over epoxide groups present in the ester, which can easily undergo an opening reaction with hydroxyl groups in the macrocyclic system. Initially, epoxidation reactions were carried out with pure conformers, and it was observed that the react...

This chapter discusses two protocols that are used throughout the remaining chapters. These protocols and experimental data comprise the early preliminary work of this dissertation. The first protocol is the synthesis of photocrosslinkable glycidyl methacrylate modified hyaluronic acid (GMHA). This derivative was synthesized by the reaction of glycidyl methacrylate with HA in a solvent mixture ...

3D printing is a manufacturing technique based on the structuring of parts layer by layer. This principle yields specific direction, that spatial orientation produced layers. Thus, potential anisotropy arising from direction major concern in printing. The mechanical properties biocompatible resin mainly consisting methacrylates and tricalcium phosphate particles examined. Various tests are cond...

The objectives of this study were to investigate the effects of dental adhesives containing quaternary ammonium methacrylates (QAMs) with different alkyl chain lengths (CL) on ecological caries prevention in vitro. Five QAMs were synthesized with a CL = 3, 6, 9, 12, and 16 and incorporated into adhesives. Micro-tensile bond strength and surface charge density were used to measure the physical p...

The dielectric relaxation of benzyl alcohol substitutents (benzyl alcohol, m-methylbenzyl alcohol and m-nitrobenzyl alcohol) with methyl methacrylate and butyl methacrylate in dilute solution of carbon tetrachloride is measured at 9.37 GHz using Frequency domain (X-band) technique. Different dielectric parameters like dielectric constant (ε'), dielectric loss factor (ε'') at Microwave frequency...
