The term epoxy is familiar to nonchemists because of the widespread use of epoxy glues and resins. These are crosslinked polyether thermoplastics made from a liquid resin which is typically a mixture of bisphenol A diglycidyl ether (70) and a polymer (71 Scheme 86). The liquid resin is cured or hardened to the final resin by mixing with a crosslinking reagent, which can be an acid, a di- or poly-alcohol, or a di- or poly-amine (Scheme 86). 

Two groups of sucrose derivatives of herbicidal acids have been reported. The herbicidal properties of the sucrose esters of (2,4-dichlorophenoxy)-acetic acid and other analogs differed somewhat from the salts of the free herbicide acids. This could be accounted for as being due to differences in solubility and penetration, since it is unlikely, by analogy to the fatty acid esters, that the sucrose esters would remain intact in the plant. 0 The second set of sucrose esters were water-soluble sirups, having surfactant properties, prepared from reaction products of hydroxyethyl ethers of sucrose or diglycidyl ethers of poly(oxyetbylene glycol) with (2,4,5-tri-chlorophenoxy) acetic acid or other herbicidal acids. 1... 

Acetylcholineesterase and choline oxidase Immobilization of horseradish peroxidase in the redox polymer poly (4-vinylpyridine-chlorobis-(2,2 -bipyridyl) osmium cross-linked by means of polyoxyethylene 400 diglycidyl ether on polished vitreous carbon electrodes. Response time of 30 s and maintained its sensitivity for 24 h at low substrate concentration. Responses were rectilinear up to 10 mM H202 for 100 pM choline with detection limit of 10 nM and 1 pM.

Epoxy-Terminated Poly (butadiene-co-acrylonitrile) (ETBN). A mixture of 730 g of bisphenol A diglycidyl ether (5.4 mol epoxy/kg), 200 g of carboxy-terminated poly (butadiene-co-acrylontrile) (Hycar 1300 x 13 from BFGoodrich, 26 wt% acrylonitrile content, acid number of 32 mg KOH/g), 64 g of bisphenol A, and 5 g triphenylphosphin was heated at 130 °C for 3 h to yield ETBN with a viscosity of 130,000 mPa-s (40 °C) and 3.3 mol epoxy/kg. 

The preferred polyol is a polyether triol (MW of 4700-5000 daltons), with a terminal poly[EO] block (13-15% EO). The preferred epoxy resin is a liquid one, the diglycidyl ether of bisphenol A (DGBA), and the hardener is ethylenediamine (EDA). The molar ratio of epoxy resin EDA is around 0.8-1 1.
