The cobalt catalyst for the co-polymerization of epoxides with GO2 was first reported in 1979 by Soga et all Gobalt acetate co-polymerizes PO with GO2 to give the almost completely alternating co-polymer, yet with a quite low catalytic activity. For the next quarter of a century, cobalt-based catalyst for the co-polymerization was not developed. 

The enzyme is present in large amounts in acetogenic bacteria, where it is involved in an unusual pathway for fixation of C02 with the formation of acetate (25,26). In acetogens this reaction is involved both in production of energy, with acetate as a waste product, and in biosynthesis of cell constituents starting from acetate. CO oxidoreductase is also present in methanogenic bacteria, where it is used in biosynthetic metabolism (25, 27). 

For example, in an investigation of silanes as adhesion promoters for ethylene/ vinyl acetate co-polymer encapsulants reported by Koenig et aL, the organo-silanes (referred to as primers ) were shown to generate primary chemical bonds at the polymer/substrate interface [27].

A novel synthesis of a-carboxyl, co-amino heterodifunctional polystyrene and its intramolecular cyclization was reported. Cyclic polystyrene with controlled size was synthesized by the intramolecular cyclization of linear a-carboxyl, co-amino heterodifunctional polystyrene under high dilution in the presence of 2-chloro-l-methylpyridinium iodide [67]. The linear precursor polymer was derived from a-diethyl acetal, co-amino heterodifunc-... 

Acyl chloride-functionalized SWCNTs are also susceptible to reactions with other nucleophiles, e.g. alcohols. Haddorfs group reported the preparation of soluble ester-functionalized carbon nanotubes SWCNT-COO(CH2)17CH3 (Fig. 1.6a) obtained by esterification with octadecanol [134]. The syntheses of soluble polymer-bound and dendritic ester-functionalized SWCNTs have been reported by Riggs et al. by attaching poly(vinyl acetate-co-vinyl alcohol) (Fig. 1.6b) [135] and hydrophilic and lipophilic dendron-type benzyl alcohols [119], respectively, to SWCNT-COC1 (Fig. 1.6c). These functional groups could be removed under basic and acidic hydrolysis conditions and thus additional evidence for the nature of the attachment was provided [119, 136].

Cobalt-Uranyl Acetate TS Dissolve, with warming, 40 g of uranyl acetate [U02(C2H302)2-2H20] in a mixture of 30 g of glacial acetic acid and sufficient water to make 500 mL. Similarly, prepare a solution containing 200 g of cobaltous acetate [Co HsC A O] in a mixture of 30 g of glacial acetic acid and sufficient water to make 500 mL. Mix the two solutions while still warm, and cool to 20°. Maintain the temperature at 20° for about 2 h to separate the excess salts from solution, and then filter through a dry filter.

Other electron-acceptor ligands can take the place of CO, for example S02. There is a series of higher clusters Pd (CO)x(PR3), (n = 3-8, 10, 16, and 23) they form on reduction of Pd salts in the presence of CO and PR3. Mixed-valence clusters may also arise in a self-assembly fashion, for example, (18-H-III) is formed from palladium acetate, CO, H+, and Ph2PCH2PPh2 (dppm).4...

Diynes. The (propargyl acetate)Co,(CO)s complex 1 couples with the trialkyn-ylalane 2 in CH2CI2 at 0° (or better, —78°) to give, after aqueous work-up, the diyne complex 3. The free diyne (4) is obtained by demetallation with CAN. 

Hot-melt adhesives are applied in molten form and a bond forms between the substrates on cooling. These adhesives are used mainly for high-speed operations such as container formation and for some pressure-sensitive labels. The archetypal hot-melt adhesive is sealing wax, but nowadays they are mainly synthetic products such as high molecular weight ethylene-vinyl acetate co-polymers. 

Poly[styrene-co-(2-hydroxy-4 -vinylbenzophenone)] was less efficient in PS than 2-hydroxy-4-methoxybenzophenone [334]. Similarly, PE films doped with 4-dodecyloxy-2-hydroxybenzophenone (0.1 mol%) were more stable than PE doped with copolymers of ethylene with polymerisable benzophenones having a comparable content of chromophores [54]. The efficiency of a SAN type LS, a terpolymer of 2-hydroxy-4-(4-vinylbenzyloxy)benzophenone with acrylonitrile and styrene did not exceed that of conventional LS [84]. No efficiency loss of 2-hydroxy-4-methacryloyloxybenzophenone in ABS was observed after bonding into a terpolymer with styrene and acrylonitrile. The homopolymer was slightly inferior to both the monomer and terpolymer [84]. A better protection of PP was provided by poly[(2-hydroxy-3-allyl-4-methoxyphenylbenzophenone)-co-dibutyl maleate] than with 2-hydroxy-3-allyl-4-methoxybenzophenone [335] (stabilization tests were performed in the presence of phenolic antioxidants). A comparable or better light stabilizing efficiency of poly[vinyl acetate-co-(5-methylacryloyloxy salicylate)] or poly(2-allylphenyl salicylate-co-dioctyl maleate) than that of alkyl-phenyl salicylates was observed in polyolefins [335].
