Module 8 Portage 219 Organic Chemistry
Polymer - correct answerslarge molecule made by repetitive linking of smaller units (monomers)
Macromolecule - correct answersvery large molecule composed of thousands of covalently
bonded atoms (ex: polymer)
1. natural (in nature)
2. synthetic (in lab) - correct answerstwo ways polymers are made
rubber, carbs: starch & cellulose, proteins, nucleic acids DNA, RNA - correct answersnatural
polymers
nylon, teflon, styrofoam, polyethylene, Dacron, - correct answerssynthetic polymers
1. method of formation
2. final composition
3. stereochemical orientation - correct answers3 main ways to differentiate polymers
1. chain-growth
2. step-growth - correct answersTwo classifications of Synthetic polymers
addition polymers - correct answerschain growth polymers are also know as:
made by addition of one monomer unit to another in a repetitive pattern - correct answersHow
are chain growth polymers made?
chain growth polymerization - correct answersA polymerization involving sequential addition to
monomers that are unsaturated (C=C) or have some other reactive functional groups
(particularly ethylene and derivatives)
1. intervention
2. consumption of all available monomers - correct answerswhat 2 things stops chain growth
polymerization?
