Q

how is an addition polymer formed

A

when thousands of alkene molecules join together
the double covalent bond opens up and becomes a single carbon bond

Q

what are the main products of condensation polymerisation

A

main product is the polymer but you also get a smaller molecule usually water

7
Q

how condensation polymerisation work

A

there are two monomers used
each monomer has a functional group at both ends of its molecule
the functional groups react to form long polymer chains

Q

what is a polyester

A

formed from a diol (alcohol containing two -OH groups)
the monomers link together and polymerise by ester links and a water molecule is given off

17
Q

how is dna made

A

condensation polymerisation of the monomer nucleotides so it is known as a polynucleotide

18
Q

what does the dna molecule consist of

A

a double helix made of two long polymer strands

19
Q

what do the 4 different nucleotides consist of

A

amino acids attached to a sugar called deoxyribose and a phosphate group

20
Q

what is the reaction fir a diol and dicarboxylic acid

A

produces polyester + water
