CB[n] are highly symmetrical macrocyclic hosts composed of glycoluril units linked through methylene bridges, and they possess highly polar carbonyl portals with a hydrophobic cavity [16].
As the years pass, more convenient and mild oxidizing agents such as 1,3,4,6-tetrachloro-3[alpha],6[alpha]-diphenyl glycoluril (Iodogen) have been developed [90].
1) is a family of relatively new, pumpkin-shaped cavitands composed of n glycoluril units linked by a pair of methylene groups.
Cucurbit[n]urils (CB[n], n = 5-8 of glycoluril units) are a class of barrel-shaped macrocyclic hosts with symmetric carbonyl-lined portals [10-16].
(32) Examination of the patent literature related to this product class (36), (37) indicates HEAT thickeners are prepared by the reaction between multifunctional methylolated amines (e.g., melamine, glycoluril) and polyethylene glycols followed by the incorporation of long chain hydrocarbon hydrophobes.

Crosslinking latex systems based on acrylamide monomers or glycoluril resins are possible under milder conditions, using latex bound -COOH groups if the latex is first ion-exchanged to convert the acid groups to the -COOH form.
The use of TGIC (triglycidyl isocyanurate) has suffered a rapid decline in recent years as the material was classified as a "Category 2 mutagen." Hydroxyalkylamide (HAA), tetramethoxymethyl glycoluril (TMMGU) and glycidyl methacrylate (GMA) have been developed as TGIC replacements.
