Module 6 None-Metallic Materials Objective Two

Question 1

Polymers

Answer 1

a major group of non-metallic materials “Plastics” many are malleable and exhibit high plastic deformation and corrosion resistance

Question 2

Polymerization

Answer 2

the joining of many monomers through chemical reactions

Question 3

chain growth (addition polymerization)

Answer 3

the rapid growth of long linear chains of molecules (Thermoplastic polymers)

Question 4

Step growth (condensation polymerization)

Answer 4

each monomer has multiple reaction sites and all monomers react simultaneously to form a single molecule (thermosetting polymers)
