Polymer films prepared by Hayes [3] consisting of bis(2-hydroxyethyl)tere-phthalate, lactic acid, tris(2-hydroxyethyl)trimellitate, ethylene glycol, poly (ethylene glycol), and the colorant titanium dioxide were both biodegradable and compostable. 

Virtually all of the organo derivatives of CA are produced by reactions characteristic of a cycHc imide, wherein isocyanurate nitrogen (frequendy as the anion) nucleophilically attacks a positively polarized carbon of the second reactant. Cyanuric acid and ethylene oxide react neady quantitatively at 100°C to form tris(2-hydroxyethyl)isocyanurate [839-90-7] (THEIC) (48—52). Substitution of propylene oxide yields the hydroxypropyl analogue (48,49). At elevated temperatures (- 200° C). CA and alkylene oxides react in inert solvent to give A/-hydroxyalkyloxazohdones in approximately 70% yield (53). Alternatively, THEIC can be prepared by reaction of CA and 2-chloroethanol in aqueous caustic (52). THEIC can react further via its hydroxyl fiinctionahty to form esters, ethers, urethanes, phosphites, etc (54). Reaction of CA with epichlorohydrin in alkaline dioxane solution gives... 

All lene Oxides and Aziridines. Alkyleneamines react readily with epoxides, such as ethylene oxide [75-21-8] (EO) or propylene oxide [75-56-9] (PO), to form mixtures of hydroxyalkyl derivatives. Product distribution is controlled by the amine to epoxide mole ratio. If EDA, which has four reactive amine hydrogens, reacts at an EDA to EO mole ratio which is greater than 1 4, a mixture of mono-, di-, tri,-, and tetrahydroxyethyl derivatives of EDA are formed. A 10 1 EDA EO feed mole ratio gives predominandy 2-hydroxyethylethylenediamine [111-41-1], the remainder is a mixture of bis-(2-hydroxyethyl)ethylenediamines (7). If the reactive NH to epoxide feed mole ratio is less than one and, additionally, a strong basic catalyst is used, then oxyalkyl derivatives, like those shown for EDA and excess PO result (8,9). 

Hayes [5] prepared a five component biodegradable blend that was used in melt blown containers consisting of bis(2-hydroxyethyl)-terephthalate, (IV), lactic acid, tris(2-hydroxyethyl)-trimeUitate, (V), ethylene glycol, and poly(ethylene glycol) using manganese (II) acetate tetrahydrate and antimony(III) oxide as initiators.

Narasimhan et al. (194) instituted a new approach to the synthesis of furoquinoline alkaloids by introducing a C2 side chain into a preformed quinoline nucleus. Lithiation of 2,4-dimethoxyquinoline, 2,4,6-tri-methoxyquinoline, and 2,4,8-trimethoxyquinoline with n-butyllithium in ether and subsequent reaction with ethylene oxide furnished hydroxyethyl derivatives 237, which with 20% hydrochloric acid were converted into dihydrodictamnine (239), dihydropteleine (240), and dihydro-y-fagarine...

Cyanopropyl bonded packing has been described as suitable for the separations of human type I-III collagens. Other stationary phases should also be mentioned LiChrosorb Diol, TSK-SW gels and Separon HEMA 1000 Glc (a copolymer of 2-hydroxyethyl methacrylate and ethylene dimethacrylate covalently bonded with glucose). The first two phases are widely used for the separation of a number of proteins, but the use of the last phase (HEMA) is mainly used for the separation of collagens. The elution is performed by isocratic conditions with 0.2 M NaCl-2 M urea-0.05 M Tris/HCl (pH 7.5) as the mobile phase. This enabled the separation of a-, 3-, and y-chains...

Photomechanical effects have also been examined for easily deformed swollen gels. This approach was first tried by Van der Veen and Prins [11] for a system consisting of water-swollen membranes of poly(2-hydroxyethyl methacrylate) cross-linked with 1.1 vol% ethylene glycol dimethacrylate in the presence of chrysophenine G (see following structure).
