What are the two types of polymerisation?
Addition and Condensation
When is an addition polymer formed?
When unsaturated monomers react to form a polymer.
Monomers contain C=C bonds.
Why are poly(alkenes) non-biodegradable?
Poly(alkenes) are chemically inert due to the strong C-C and C-H bonds and non-polar nature of the bonds and therefore are non-biodegradable.
When do chains form?
Chain forms when same basic unit is repeated over and over.
Draw the polymer for But-2-ene.
What are the two most common types of condensation polymers?
polyesters and polyamides which involve the formation of an ester linkage or an amide linkage.
