3.3.12 Polymers

Where 2 different monomers with at least 2 functional groups react.
Form link and water removed

Via reacting dicarboxylic acids and diamines. Forms AMIDE LINK
OH removed from acid and H removed from amine

Polyamide for bulletproof vest,car tyres
Made from benzene-1,4-dicarboxylic acid and 1,4-diaminobenzene

Polyamide for ropes,clothing, carpet
Made from hexanedioc acid and 1,6 diaminohexane

React dicarboxylic acids and diols and forms ester links and releases H20

Polyester for bottles,clothes,sheeting
Made from benzene-1,4-dicarboxylic acid and ethane-1,2-diol

Can be hydrolysed via water to produce original monomers.
Straight up reverse

Have polar bonds by C-O and C-N which can interact with other chains and form strong INFS.
So they are susceptible from nucleophile attacks.
Biodegradable and broken down by hydrolysis slowly unlike addion polymers

Landfill
Incineration
Recycle

Landfill useful for disposing plastics which are too difficult to recycle/not worth doing
The decomposition leads to greenshouse gases and risk of water contamination via leaching
Not sustainable and expensive

Incineration can be used for unrecyclable plastic.
Energy from burning can be used to generate electricity
Produces toxic fumes and flue gas scruppers used to netrulastix acidic gas(hcl)

Recycling leads to less dependency on crude oil
Some plastic can be recycled and remoulded
