polymerization Flashcards
what is polymerization?
an addition reactions which alkenes can undergo to form plastics (polymers)
what are polymers made from?
polymers are built by linking 50 or more smaller molecules called monomers
how is each polymer connected to one another?
they are connected in a repeating pattern through covalent bonds
how is polyethene made?
by the addition polymerisation of many ethene monomers
how should the atoms in polymers be arranged in the displayed formula?
they should be arranged in a capital “H” shape
what kind of bonds do monomers need to have to form polymers?
can only occur in monomers with DOUBLE C=C bonds
how does the bond breaking and making work when forming polymers?
One of the bonds in each C=C bond breaks and forms a bond with the adjacent monomer
the polymer has single bonds only
how do you name polymers?
by putting the name of the monomer in brackets and adding poly- as the prefix
ex: with propene - poly(propene)
what polymer does but-2-ene make?
what polymer does 2,3 di-chloropent-2-ene make?
what polymer does 1,1-dibromo-3,3-difluoro propene make?
