To solve this problem, Yokohama Rubber mixed an acid acceptor
into the polyamide resin to enable it to capture and hold the acid runoff.
It can be seen from Figure 4 that electrons transfer from the amino donor to the benzoic acid acceptor
. In gas, the maximum absorption peak is 452 nm (463 nm in solvent), and the oscillator strength is 0.5880 (0.7021 in solvent).
The HOMO-2 electron densities are localized in the bithiophene bridge and cyanoacrylic acid acceptor
. While the LUMO levels are largely dominating contributions from the [pi]*-orbitals of the cyanoacrylic acid and the nearby [pi]-linkers, which facilitate the electron charge transfer from the donor to acceptor.
Haistab 1214 is a nontoxic acid acceptor
for rigid PVC that reportedly improves the performance of organotin heat stabilizers in extruded products, such as vinyl siding or profile.
Users gain the flexibility of producing a wide range of end-use tailored compounds from either reactor flake or granule or from a basic compounded pellet containing only antioxidant and acid acceptor
. According to Eastman's calculations, a 220-million-lb/yr resin plant could spend $1.5 million for equipment to apply the Aquastab coatings, using six operators.
The optimization of the acid acceptor
system, particularly the amount of magnesium oxide used (refs.
HSA 10 is a micronized, high activity MgO for use as a scorch retarder in chloroprene and fluoroelastomers, as a thickening agent for SMC/BMC, and as an acid acceptor
in halogenated and chloroprene adhesives.
If the next higher UL rating, 105 [degrees] C, is desired, this is also readily accomplished (table 4) by using a less volatile plasticizer, a more efficient acid acceptor
, and an antioxidant which will not interfere with a peroxide cure.
Now, magnesium hydroxide is an acid acceptor
. Indeed, its classic and wide spread use in both liquid and tablet antacid formulations is based on its ability to neutralize acids.
Elesh, Spectroscopic and physical measurements on charge-transfer complexes: Interactions between norfloxacin and ciprofloxacin drugs with picric acid and 3,5-dinitrobenzoic acid acceptors
Viton is a fluorocarbon resin that is mixed with a filler, such as carbon black; acid acceptors
, such as magnesium oxide (MgO); and curing agents before being cured into a fluoroelastomer material and sold as Viton O-rings.
Additional process factors that increase costs are rheological variability due to hygroscopic acid acceptors
, mold sticking and difficulty dispersing an additional compound ingredient, calcium hydroxide.
