  1. 1What determines the properties of plastics?Forces between molecules
  2. 2What happens with plastics if there are weak forces?Individual tangled chains of polymers, held together by WEAK INTERMOLECULAR FORCES are FREE TO SLIDE OVER EACH OTHER
  3. 3Thermosoftening polymers and forces1. Don't have cross-linking chains
    2. Forces between chains are easy to overcome- easy to melt the plastic
    3.when it cools, it will harden into a new shape
  4. 4Strong forcesSome plastics have strong intermolecular forces between the polymer chains- crosslinks e.g. THERMOSETTING POLYMERS
