The use of surfactants that are also able to bind molecules of interest has long been of interest in the preparation of molecularly imprinted polymers, prepared by emulsion polymerization processes [12-21]. Surfactants containing functionality capable of binding to metal ions have been used in emulsion polymerization. The bifunctional surfactant l,12-dodecane-diol-0,0 -diphenyl phosphonic acid (Fig. 3) was used in the synthesis of polymers imprinted with zinc ions in a water in oil emulsion [22]. This a,co-functional surfactant sits at the interface between the organic and aqueous phases during polymerization.

Water-borne polyurethane coatings are formulated by incorporating ionic groups into the polymer backbone. These ionomers are dispersed in water through neutrali2ation. The experimental 1,12-dodecane diisocyanate (C12DI Du Pont) is especially well suited for the formation of water-borne polyurethanes because of its hydrophobicity (39). Cationomers are formed from IPDI, /V-methyIdiethan olamine, and poly(tetramethylene adipate diol)...

The peracid methods invariably open the epoxide with reversion of configuration, i.e. trans-diol formation. Aryl substituents, however, are converted to the cw-diols with retention of configuration.118-120 Olefins which have been hydroxylated by means of in situ percarboxylic acid techniques include cyclohexene (65-73%),121 dodecane (91 %)122 and oleic acid (99%).123 Chlorestrol has been frans-hydroxylated with performic acid in high yield (91%).124... 

Figure 6A Chromatographic separation, of the Neutrals fractions from the Light and Medium Dark Lithotypes. Numbers directly above eluted peaks identify the chain length of these even n-alcohols. Numbers below the chromatogram refer to the carbon chain length of the corresponding terminally hydroxylated diols. (X) is identified as 1,9-dihydroxy-dodecane.

Pyrolysis process for poly(2-hydroxyethyl methacrylate) occurs similarly to that for other methacrylic acid esters. The formation of 2-methyl-2-propenoic acid 2-hydroxyethyl ester, the monomer, shows that unzipping is a significant part of the process. Some other compounds in the pyrolysate also are generated from the polymer cleavage, such compounds including 2-methyl-2-propenoic acid ethenyl ester, propanoic acid, 2-methyl-2-propenoic acid, ethanol, etc. On the other hand, some compounds are not expected in the pyrolysate and they can be impurities or additives. Examples of such compounds are the hydrocarbons (undecene, dodecane, 1-dodecene, etc.), the esters of ethylene diol and the free 1,2-ethandiol, etc. The initiator AIBN and its decomposition products 2-methyl-2-propenenitrile and 2-methylpropanenitrile identified in the pyrolysate show that the polymer was obtained using AIBN as initiator. 

Carbenes, generated by photolysis of di- and tetrachloro-o-quinone diazides, react with oxetane in a 1 3 ratio to afford 15-membered crown ethers. Benzocrown ether 675 was obtained in 16% yield (91CB1865). Derivatives of macrocyclic crown ethers with four or five oxygen atoms in a ring were synthesized by Cu(acac)2-catalyzed cyclization of a,polyethylene glycols. 20-26-Membered crown-4(5) ethers 676 were prepared from the above-mentioned diazo ketones with tri- or tetra-ethylene glycols in 7-26% yields. Treatment of l,8-bis(diazoacetyl)octane with dodecane-l,12-diol under the same conditions results in a mixture of 52-membered tetraether 646 (40%) and compound 645 (81CC616). 

The light-induced bromination of cii,(rani-perhydro-9b-boraphenalene (3b) in the presence of water proceeds selectively at the a-tertiary hydrogen atom (bromide (44)) to produce a polycyclic borinic acid (45) under the action of water. Oxidation of the latter provides bicyclo[7.3.0]dodecane-1,5-diol (46) in 70% yield (Scheme 17) (74JOC86l>.

The fourth diol of this crystallographic family is syn-28-dihydroxy-2,8-dimethyItricydo[5.3.1. dodecane (7). Crystals grown from benzene (7B) have the structure shown in Figure 5 with a six-lobed canal cross section. 

The photo-cured poly(diol-tricarballylate) (PDT) degradable bioelastomers were prepared based on the polycondensation reaction between tricarballylic acid and alkylene diols such as 1,6-hexanediol, 1,8-octanediol, 1,10-decanediol and 1,12-dodecanediol, followed by acrylation and photo-cross-linking, as shown in Scheme 8.29.The PDT prepolymers, such as poly(l,6-hexane diol-co-tricarballylate) (PHT), poly(l,8-octane diol-co-tricarballylate) (POT), poly(l,10-decane diol-co-tricarballylate) (PDET and poly(l,12-dodecane...
