Polymers
Cards in this deck (5)
- 1What determines the properties of plastics?Forces between molecules
- 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
- 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 - 4Strong forcesSome plastics have strong intermolecular forces between the polymer chains- crosslinks e.g. THERMOSETTING POLYMERS
- 5What will affect the properties of a polymer?The starting materials and reaction conditions
