C11:Polymers Flashcards
what are plastics made from
very large covalently bonded molecules called polymers
what is a polymer
long chain of monomers
what is a monomer
single molecule
how are large polymers made
when many monomers join together
addition polymerisation
the reaction between alkene monomers to form a polymer
how do addition polymers work
the repeating unit has the same atoms as the monomer because when the C=C bond opens up in polymerisation no other molecule is formed
difference between condensation polymerisation and addition polymerisation
in condensation polymerisation usually, a small molecule is formed as the polymer is formed
condensation polymerisation
the monomers are usually different with two of the same functional group on each monomer
how are polyesters formed in condensation polymerisation
diol+dicarboxylic acid= polyester+ water
another name for simple carbohydrates
monosaccharides
what do simple carbohydrates polymerise to form
polymers such as starch and cellulose
what are protein polymers made from
different amino acid monomers
in condensation polymerisation what do amino acids react to form
polypeptides and proteins
what two groups do amino acids have
an acidic and a basic functional group
what does DNA stand for
deoxyribonucleic acid
