Module 8 Portage 219 Organic
Chemistry 100% Verified Solutions
Polymer
large cmolecule cmade cby crepetitive clinking cof csmaller cunits c(monomers)
Macromolecule
very clarge cmolecule ccomposed cof cthousands cof ccovalently cbonded catoms c(ex: cpolymer)
1. natural c(in cnature)
2. synthetic c(in clab)
two cways cpolymers care cmade
rubber, ccarbs: cstarch c& ccellulose, cproteins, cnucleic cacids cDNA,
cRNA cnatural cpolymers
,nylon, cteflon, cstyrofoam, cpolyethylene,
cDacron, csynthetic cpolymers
1. method cof cformation
2. final ccomposition
3. stereochemical c orientation
3 cmain cways cto cdifferentiate cpolymers
, 1. chain-growth
2. step-growth
Two cclassifications cof cSynthetic cpolymers
addition cpolymers
chain cgrowth cpolymers care calso cknow cas:
made cby caddition cof cone cmonomer cunit cto canother cin ca crepetitive
cpattern cHow care cchain cgrowth cpolymers cmade?
chain cgrowth cpolymerization
A cpolymerization cinvolving csequential caddition cto cmonomers cthat care cunsaturated c(C=C) cor
chave csome cother creactive cfunctional cgroups c(particularly cethylene cand cderivatives)
1. intervention
2. consumption cof call cavailable cmonomers
what c2 cthings cstops cchain cgrowth cpolymerization?
Teflon
chain-growth
polymer: cpolytetrafluoroethylene
cmonomer: cF2C=CF2
nonstick ccoating, cgoretex, celectrical cinsulator, cchem-resistant ccoating
