Physical Structure
Linear polymers may be represented by a chain with two ends.
Branched polymers have side chains, or branches, of significant length which are bonded to the main chain at branch points, and are characterized in terms of the number and size of the branches. Polymers with well-controlled modes of branching: comblike polymers, star polymers, dendrimers, etc.

Crystalline polymers Invariably do not form perfect crystalline materials but instead are semicrystalline with both crystalline and amorphous regions. The crystalline phase of such polymers are characterized by their melting temperature (Tm).

Thermosets Rigid materials and network polymers in which chain motion is greatly restricted by a high degree of crosslinking. Intractable once formed. Degrade rather than melt upon heating.

Classification of synthetic polymers
• Classification according to: – Physical structure – Thermal behaviour – Use – Preparation method
Thermoplastics (plastics)
Linear or branched polymers which can be melted
upon the application of heat. (Largest proportion of
the polymers used in industry.)
Network polymers have three-dimensional structures in which each chain is connected to all others, and are characterized by their crosslinking density or degree of crosslinking (number of junction points per unit volume).
