addition polymers

Cards (8)

what reaction joins together alkenes?
addition polymerisation
what are the conditions of addition polymerisation?
high pressure
catalyst
what are the equations for addition polymerisation?
monomer ---> addition polymer
alkene ---> polyalkene
why are polyalkenes unreactive?
saturated
what are features of PVC?
brittle and hard
they can be softened and made more flexible by adding plasticisers
what are uses of uPVC?
rigid - dipole-dipole between polymer chains in regular arrangement
used in windows and doors
what are uses of PVC?
flexible - dipole-dipole between polymer chains interrupted by plasticiser
used in footwear and clothing
why are polyalkenes non-biodegradable and non-degradable?
held together by Van der Waals forces
