Week2) Jove videos, Polymers Flashcards
what is a polymer?
chain of small molecules called monomers that are held together by covalent bonds
natural polymers- building blocks of life
DNA, Polysaccharides, Proteins, Lipids
organism can synthesize
biological polymers
scientists can synthesize
polymers in the laboratory
common synthetic polymers?
Plastics- incude Nylon, Polyethylene, teflon
Process of monomers linking to each other to form a larger molecule is known as?
Polymerization
Monomers polymerize by 2 sistinct reaction mechanism
- Condensation, Addition
condensation polymorezation
- 2 monomers with reactive hydrogen atom and hydroxyl group, respectivily link to each other, with the realse of water as a by products
- most natural polymers are formed by condasation reaction
Addition polymerization
- Monomers with carbon- carbon double bonds are added to eachother to form a polymer without the generation of any by products through the release of atoms.
polymers made up of the same type of monomers known as?
homopolymers
Polymers made up of different types of monomers known as?
Heteropolymers
cellulose is a
