Exam points

  • identify the polyalkene backbone as containing strong, non-polar C–C and C–H bonds
  • state that the chain lacks polar ester or amide links that water or enzymes can hydrolyse
  • link this chemical inertness to resistance to biological degradation rather than simply calling the polymer strong
