Questions And Answers
\.Polymer - Answer- large molecule made by repetitive linking of smaller units (monomers)
\.Macromolecule - Answer- very large molecule composed of thousands of covalently
bonded atoms (ex: polymer)
\.1. natural (in nature)
2. synthetic (in lab) - Answer- two ways polymers are made
\.rubber, carbs: starch & cellulose, proteins, nucleic acids DNA, RNA - Answer- natural
polymers

3. stereochemical orientation - Answer- 3 main ways to differentiate polymers
\.1. chain-growth
2. step-growth - Answer- Two classifications of Synthetic polymers
, \.addition polymers - Answer- chain growth polymers are also know as:
\.made by addition of one monomer unit to another in a repetitive pattern - Answer- How
are chain growth polymers made?
\.chain growth polymerization - Answer- A polymerization involving sequential addition to
monomers that are unsaturated (C=C) or have some other reactive functional groups
(particularly ethylene and derivatives)
