?
Hydrogen bonding
hydrogen atom attached to NOF with a lone pair of electrons (**)
1 of 25
Permenant dipole
large difference in electronegativety between to polar molecules
2 of 25
Instantaneous induced dipole
electron movement, form charge cloud = temporary dipole
3 of 25
Electronegativety
ability to attract bonding electrons in a covalent bond
4 of 25
Primary amine
H - N(**) (-H) - R
5 of 25
Secondary amine
H - N(**) (-R) - R
6 of 25
Tertiary amine
R - N(**) (-R) - R
7 of 25
Amine properties
Basic, soluble, ligand & nucleophile
8 of 25
Amide
R - C (=O) - N (-H) - R
9 of 25
Addition polymerisation
breaking of a double carbon bond
10 of 25
Condensation polymerisation
water formed as a by product of the reaction
11 of 25
Polamide
Dicarboxylic acid + Diamine
12 of 25

Amide
14 of 25
Tm
Melting temperature- soften
15 of 25
Tg
Glass transition temperature- no longer glassy
16 of 25
Crystalline
Straight chain, closer = stronger intermolecular forces (ordered)
17 of 25
Amorphous
Not ordered = weaker intermolecular forces
18 of 25
Cold drawing
Extending polymer, increase crystallinity
19 of 25
Co-polymerisation
Adding different polymers to alter shape, decreases bond strength
20 of 25
Plasticiser
Adding small molecules between chains, increases flexibility
21 of 25
Amide + dilute acid ->
Carboxylic acid + Ammonia salt
22 of 25
Amide + dilute alkali ->
