Amorphous nylons are transparent. Heat-deflection temperatures are lower than those of filled crystalline nylon resins, and melt flow is stiffer hence, they are more difficult to process. Mold shrinkage is lower and they absorb less water. Warpage is reduced and dimensional stabiUty less of a problem than with crystalline products. Chemical and hydrolytic stabiUty are excellent. Amorphous nylons can be made by using monomer combinations that result in highly asymmetric stmctures which crystalline with difficulty or by adding crystallization inhibitors to crystalline resins such as nylon-6 (61). 

AN prills (74), Na nitrate (2), w (16), urea (5.5), guar gum (0.4), Zn chromate (0.1), and naphthalene (2.0%). Francis (Refs 15 16) claims the use of urea primarily as a crystallization inhibitor for compns which when detonated in 2" and 3" diam schedule 40 steel pipe, using from 10 to 25g of 0-4 compn as the initiator, yielded deton velocities in the range of from 4663 to 6126m/sec. Typically, a mixt comprising urea (4), AN (21.3), guar gum (0.7),...

On the basis of this information, we predicted that replacement of the amide group of PAN with another amide bound to a polymer-chain will generate a most efficient crystallization inhibitor. According to our analysis we prepared polymer 14 and... 

Water, occasionally modified by ethanol and salt, is the universal food solvent. Vj and vm are maximum in pure water and minimum in pure ethanol. Without hydration, polysaccharides cannot perform as plasticizers, thickeners, texturizers, stabilizers, crystallization inhibitors, and bulking and gelling agents. Crosslinking holds vm constant, irrespective of the solvent. All water relationships with solute theoretically disappear at 0.

It should be noted that the saturated fractions are a natural portion of the product and that this fallout is a natural characteristic of the product. Some users have requested methyl lardate with lower levels of fallout or no fallout. In an attempt to provide this product, manufacturers have blended certain crystal inhibitors. Up to 15% methyl esters of less saturated vegetable oils have been blended in to reduce cloud point and fallout, but some problems may result as the unsaturated fatty esters perform differently in high heat metalworking processes. However, vegetable oils are typically more expensive than the rendered fats, and the practice of blending in methyl esters of vegetable oils makes the resultant product more expensive.
