Chapter 20 - Petrochemicals and Polymers Flashcards
What are polymers?
Large molecules built up from many smaller molecules called monomers
what are plastics made of?
Polymers
What environmental issues do plastics contribute to?
Landfill disposals
Accumulation in oceans
Formtion of toxic gases
Proteins
polyamides formed from amino acids with monomers
how to name polymers
poly(monomer)
e.g. Poly(ethene)
Polymers are made of?
Alkenes because of the double bonds
what are condensation polymers
Polyesters
Carboxylic acid + Alcohol
Polyester +water
(COO ester link remains in middle of polyester)
Why is it called a condensation polymer?
Process forms water
WHat is needed for condensation polymers AKA Polyesters
at least 2 functional groups from each monomer being bonded
2 Different functional groups overall
Small molecule given off in the process
Polyesters are
mostly biodegradeable
Refinery gas use
Heating and cooking
Gasoline use
Car fuel
Naphtha use
Chemical feedstock
Paraffin( kerosene) use
Jet fuel
