Ch. 13.5 : Polymerisation in Alkenes Flashcards
1
Q
Define polymer
A
Large molecule formed by thousands of repeating units ( monomers )
2
Q
Define monomer
A
A specific arrangement of atoms in a polymer molecule that repeats over and over again
3
Q
Describe the relationships between plastics, polymers and monomers
A
The properties of a plastic material depend on the polymer chains that make it
The properties of a polymer depend on the monomers that make it
4
Q
Describe how you would show the repeating unit of a monomer
A
Double bond broken
Square brackets with bonds extending through it
‘n’ before monomer and after polymer
5
