The polyamide copolymer of dodecanoic acid with methylenedi(cyclohexylamine) (MDCHA, PACM) was sold as continuous filament yam fiber under the tradename QIANA. As late as 1981, over 145,000 t was produced using high percentages, typically 80%, of trans, trans MDCHA isomer. The low melting raffinate coproduct left after t,t isomer separation by fractional crystallisation was phosgenated to produce a Hquid aUphatic diisocyanate marketed by Du Pont as Hylene W. Upon terrnination of their QIANA commitment, Du Pont sold the urethane intermediate product rights to Mobay, who now markets the 20% trans, trans—50% cis, trans—30% cis, cis diisocyanate isomer mixture as Desmodur W. In addition to its use in polyamides and as an isocyanate precursor, methylenedi (cyclohexyl amine) is used directiy as an epoxy curative. The Hquid diamine mixture identified historically as PACM-20 is marketed as AMICURE PACM by Anchor Chemical for performance epoxies. [Pg.213]

Epoxy crack injection systems are unfilled compositions, based on low-viscosity liquid epoxy resins and low-viscosity moisture-tolerant hardeners. The low viscosity of the system aids penetration into fine cracks and achieves the right balance of gel time (Anchor Chemicals/Air Products, undated a). Cracks as narrow as 0.05 mm can be filled with epoxy injection systems (CCA/, 1985). [Pg.72]

Anchoring chemical species on a solid support is another possibility for reagent immobilisation in flow analysis. This approach enables enzyme cartridges, ion-exchange resins and other functionalised beads to be effectively exploited. The beads are generally packed in mini-columns, and fluidisation can also be used. [Pg.321]

Again this reaction is accelerated by hydroxyl groups or tertiary amines. This is also the predominant reaction with anhydrides. In fact, reactions with resin and hardener or catalyst are very much more eomplex than these idealized reactions, and both reactions as well as a number of side reaetions probably oeeur to varying extents in any cross-linking mechanism. Major suppliers of euring agents inelude Anchor Chemicals, Dow, Shell, and Cray Valley Products. [Pg.812]

A more effective approach is to use polymer chains consisting of two parts (graft or block copolymers). Figures 4.20b and 4.20c show these two types of copolymers in which one part is nominally insoluble and anchors (chemically or physically) onto the particle surface and the other is soluble in the liquid and extends into the liquid (37). Examples of commonly chosen block copolymers in organic solvents (e.g., toluene) are poly(vinyl pyrrolidone)/polystyrene (PVP/ PS) or poly(ethylene oxide)/polystyrene (PEO/PS). [Pg.214]
