Some properties of Polymers I Properties of polymers 1. Long molecules containing a chain of covalent-bonded carbon atoms 2. Molecules joined to each other by weak hydrogen bonds or Van Der Waal bonding. 3. Poor conductors of heat and electricity. 4. Very light weight . 5. Very low elastic stiffness. 6. Not very strong. 7. Very low melting temperature. 8. Very easy to fabricate polymers into complex shapes. Thermoplastic polymer (no cross-linking) Thermoset polymer (lots of cross-linking)
