What is a polymer?
A plastic
1 of 15
What are polymers made of?
Hundreds of monomers that joins together to form long chains

What is a natural polymer? give an example.
A natural polymer is a plastic formed naturally and not man-made. For example rubber, silk, proyein, DNA and starch.

What is a synthetic polymer? give an example.
A synthetic polymer is a plastic that do not form themselves, but are man-made. For example kevlar, polyester, polystyrene, polyethene and nylon.

What is the name of the bond that join the monomers between atoms?
The name of the bond that joins the momemers between atoms is a covalant bond
5 of 15
In a covalabnt bond, each atom shares something with another atom. What do they share?
each atom shares one or more electrom with another atom

Many polymers are formed from alkenes. What is an alkene?
An alkene is a hydrocarbon molecule
7 of 15
Polymers are formes form alkenes. What is the general formula for alkenes?
Cn H2n There are twice as many hydrogens that carbons in an alkene
8 of 15
Alkenes contain at least one double covalant bond between carbon atoms. How does this double bond effect the reactivity?
The double bond makes them very reactive

What is the name of the shorthand version of polymerisation?
A catalyst is the name of the shorthand version for polymerisation
