AIM
To learn about the various the raw materials, manufacturing, preparation and properties
of various nylons
OBJECTIVES
To understand Methods of manufacturing, properties and applications of commercial
nylons such as Nylon 6, Nylon 6, 6, Nylon 6, 10, Nylon 4, 6, Nylon 11, Nylon 12 etc.
Crystal structure and property relationship of nylons.Modified nylons through blends and
alloys
UNIT I 9
Historical development of nylons – commercial nylons; Polyamidation – Principle of
polyamidation – chemistry, polycondensation and equilibria – kinetics – molecular mass;
Polycondensation process techniques – hydrolytic, ionic and solid phase polymerization
UNIT II 9
Commercial nylons – nylon 6, nylon 66, nylon 6, 10, nylon 4 6, nylon 11, nylon 12 – raw
materials, method of manufacturing, properties and important applications – chemical
attack and degradation of nylons – oxidative, thermal and hydrolytic degradation
UNIT III 9
Structure - property relationship in nylons – crystallization of nylons and crystal structure
effect on molecular weight - melting temperature, Tg – crystallization growth, orientation,
morphology Characterization of nylons – identification of nylons and their hydrolysis
products for composition and moisture content by HPLC, DSC, Karl Fischer method, IR,
NMR and X ray; Molecular weight and distribution by GPC and End group analysis
method, solution viscosity method
UNIT IV 9
Processing of nylons - Rheology, PVT relationship – Effect of moisture, molecular mass,
shear, temperature, additives on melt processing; Melt Processing techniques- extrusion
into film and tube, injection moulding – RIM, blow moulding; other process techniques
such as solution coating, powder coating, blending
UNIT V 9
Modification of nylons – transparent, toughened, flame retardant, plasticized and
lubricated nylons, filled and reinforced grades; blends and alloys nylon with other
polymers – nylon 66 –PPO (Noryl), nylon 6 – LDPE, EPDM
Introduction to fibre technology – nylon 6 melt spinning, drawing into yarns - dye ability
TOTAL: 45 PERIODS
