amide

 [am´īd]
any compound derived from ammonia by substitution of an acyl radical for hydrogen, or from an acid by replacing the -OH group by -NH2.

am·ide

, primary amidesecondary amidetertiary amide (am'īd, am'id),
A substance derived from ammonia by replacing hydrogen atoms with acyl groups, R-CO-NH2. Replacement of one hydrogen atom results in formation of a primary amide; of two hydrogen atoms, a secondary amide; and of three hdyrogen atoms, a tertiary amide. Amides can also be derived from a carboxylic acid by replacing a carboxylic OH with NH2 from a carboxylic acid by replacement of a carboxylic OH by NH2. Replacement of one hydrogen atom constitutes a primary amide; that of two hydrogen atoms, a secondary amide; and that of three atoms, a tertiary amide.

amide

(ăm′īd′, -ĭd)
n.
1. An organic compound, such as acetamide, containing the CONH2 group.
2. The anion of ammonia, NH2- or a compound containing this anion, such as sodium amide, NaNH2.

a·mid′ic (ə-mĭd′ĭk, ă-mĭd′-) adj.

am·ide

(am'īd)
A substance formally derived from ammonia through the substitution of one or more of the hydrogen atoms by acyl groups, R-CO-NH2, or from a carboxylic acid by replacement of a carboxylic OH by NH2. Replacement of one hydrogen atom constitutes a primary amide; that of two hydrogen atoms, a secondary amide; and that of three atoms, a tertiary amide.

amide

a compound formed from ammonia in which one or more hydrogen atoms are replaced by a metal or acid radical.

am·ide

(am'īd)
A substance formally derived from ammonia through the substitution of one or more of the hydrogen atoms by acyl groups, R-CO-NH2, or from a carboxylic acid by replacement of a carboxylic OH by NH2.

Other slips based on secondary amides have almost twice the molecular weight of primary amides and thus migrate more slowly in polyolefins.
Introduced in the late 1990s, non-migratory slips have molecular weights 30 to 50 times greater than primary and secondary amides. Their large size does not allow them to diffuse through a polymer, so their COF reduction is provided by the slip molecules that end up on the surface during extrusion.
The performance of primary and secondary amides depends on many factors:
Akzo's new antislip agents for engineering resins--Armid OPA and Armid SSA--are secondary amides that are reportedly less volatile at higher process temperatures and can lead to higher throughput speeds.
Crodamides are a line of fatty acid amides, which include primary amides (erucamide, oleamide, and stearamide), secondary amides (stearyl and oleyl erucamide, etc.), and tertiary amides (N,N-dimethylamides).
* Kemamide S-80, E-180, P-181, S-221 and E-221 secondary amides are slip and antiblock agents, which can withstand processing temperatures surpassing 550 F.
