Polymers

Polymers are made by many repeating __________ bonded together

• monomers

• alcohols

• ionic bonds

• unsaturated chains

As polymers increase in lenght, they also increase in _______ (2 answers)

• melting points

• thermostability

• intermolecular forces

• difference in monomers

Monomers use this type of bond to form polymers

• metallic

• covalent

• ionic

• nuclear

In the condensation process this happens:

• a small molecule is lost

• the monomers are added without releasing a molecule

• alcohols are formed

• the same monomer is repeated over and over

In the addition process, this happens:

• There is a proton attack

• A small molecule is lost

• There is no release of a small molecule from the growing polymer chain

• Double bonds are formed

Homopolymers can be described as:

• A polymer formed with the same monomer repeated

• A polymer that is thermoflexible

• A polymer formed with different types of monomers

• A polymer formed by condensation

Heteropolymers can be described as:

• A polymer formed with the same monomer repeated

• A polymer that is thermoflexible

• A polymer formed with different types of monomers

• A polymer formed by condensation

An example of a natural polymer is:

• a protein

• PVC (polyvinyl chloride)

• polyethylene

• PET

Thermosets can be described as:

• polymers formed by addition reactions

• plastics that cannot be moulded once they are set with temperature and pressure

• plastics that can be remoulded everytime with temperature

• plastics formed with the monomer hexanedioic acid

This is the best type of plastic to recycle:

• thermoplastics

• thermosets

• synthetic polymers

• polyamide
