1. What is a copolymer?
2. Describe and differentiate between a random, alternating, block, and graft copolymer.
Yep, my bad.
Assuming I'm right, I'll just post the next question, to make sure I don't forget.
Describe the "melting process" for:
1. Amorphous thermoplastic polymers.
2. Crystalline thermoplastic polymers.
3. Thermoset polymers.
Amorphous plastics do not have a sharp melting point; rather, regions of the polymer soften as the temperature increases. Crystalline thermoplastic polymers have a sharp melting point and change to a liquid once that point is met fairly quickly. Thermoset polymers do not melt.
