“…Glycoluril, a biurea compound known for about 130 years, has established an impressive career as a building block for molecular and supramolecular chemistry during the past two decades. For example, glycoluril derivatives have been used in a variety of applications, including polymer crosslinking (Jacobs et al, 1996), explosives (Yinon et al, 1994), the stabilization of organic compounds against photodegradation (Krause et al, 1997), textile waste stream puri®cation (Karcher et al, 1999) and combinatorial chemistry, and furthermore in the ®elds of cucurbituril chemistry (Freeman et al, 1981;Kim et al, 2000;Pryor & Rebek, 1999;Lee et al, 2003;Burnett et al, 2003) and anion sensors (Kang et al, 2004;Kang & Kim, 2005). The intriguing structural feature in a number of glycoluril derivatives is the twisting observed about the bridgehead dihedral angle, and the rigid and nonplanar glycoluril skeleton, with well de®ned geometry, is more favourable for constructing a three-dimensional structure, which suggests that glycoluril derivatives have signi®cant potential as building blocks in crystal engineering studies.…”

Two new glycoluril derivatives, namely diethyl 6-ethyl-1,4-dioxo-1,2,2a,3,4,6,7,7b-octahydro-5H-2,3,4a,6,7a-pentaazacyclopenta[cd]indene-2a,7b-dicarboxylate, C(14)H(21)N(5)O(6), (I), and 6-ethyl-2a,7b-diphenyl-1,2,2a,3,4,6,7,7b-octahydro-5H-2,3,4a,6,7a-pentaazacyclopenta[cd]indene-1,4-dione, C(20)H(21)N(5)O(2), (II), both bearing two free syn-urea NH groups and two ureidyl C=O groups, assemble the same one-dimensional chains in the solid state running parallel to the [010] direction via N-H...O hydrogen bonds. Furthermore, the chains of (I) are linked together into two-dimensional networks via C-H...O hydrogen bonds.

“…matte finishes with gloss <5%), high clarity for automotive topcoats, high abrasion resistance and polychromatic or gonioapparent effects [14,15]. Accordingly, the influence of new resin additives like curing agents, flow promoters and extenders onto final film morphology was also widely discussed [16][17][18]. However, most publications have been mainly concerned only with the levelling of powder coatings and not with the development of matte finishes [19][20][21].…”

This study focuses on the correlation between the thermo-rheological properties of a thermosetting powder coating system with its surface structure build-up. Epoxy powder coating systems, which displayed surface matting and surface wrinkling, were examined. Firstly, the evolution of the complex viscosity was correlated with the cure kinetic. Secondly, the structure build-up on the surface of the coatings was investigated with a combined SEM-CLA profilometry analysis at different stages of curing process for both EFB and CHDFB coating processes. Different finishes were found to characterize the films applied by using EFB and CHDFB coating processes as a result of the different way the film is heated by. Finally, a strict relationship of film morphology to the degree of conversion and to the evolution of the complex viscosity was found out for both EFB and CHDFB coating processes. The surface structure is built up after gelation point and continues to evolve after gelation with a full development of the film fine structure. Differences were observed in the surface structure build-up when different curing temperature was used, thereby indicating an influence of minimum viscosity on achievable finishing.These experimental results lead to further advances in a better understanding of the formation of surface topography and morphology of polymeric films. They also provide important indications for the settings of curing parameters in both EFB and CHDFB coating processes as well as for the development of new powder coating formulations.

Abstract. Improve and illustrate the etherification of tetramethylol glycoluril using excess of methyl and ethyl alcohols in the presence of acid catalyst like HCl and HNO 3 under temperature not exceeding 55 °C. Furthermore, attempts to obtain 1,4-diphenyl 1,2-dimethylol glycoluril which is a new compound from the condensation of 1,4 diphenyl glycoluril with formaldehyde in the presence of water under mild temperature. The techniques used to identify the compounds of the present study are: FTIR spectroscopy, HPLC and 13 C NMR spectroscopy.
