Two classifications of Synthetic polymers
Correct Answer: 1. chain-growth
2. step-growth
chain growth polymers are also know as:
Correct Answer: addition polymers
How are chain growth polymers made?
Correct Answer: made by addition of one monomer unit to another in a repetitive pattern
A polymerization involving sequential addition to monomers that are unsaturated (C=C)
or have some other reactive functional groups (particularly ethylene and derivatives)
Correct Answer: chain growth polymerization
