level questions: thermosoftening and thermosetting polymers
| Question | Answer |
|---|---|
| what are the properties of polymers based on | the monomer and the conditions used to form the polymer |
| what would happen if the conditions of low density poly(ethene) were to change | high density poly(ethene) would form which is a lot stronger and harder than low density |
| what conditions could be changed to change the properties of a polymer | temp of the reaction, pressure and catalyst |
| why can thermosoftening polymers melt | the intermolecular forces between the polymer strands are weak and very easy to overcome which allow the strands to separate from one another |
| what happens when thermosoftening polymers get cooled again | the intermolecular forces between the strands reform and it turns back into a solid |
| why can't thermosetting polymers melt | in-between the polymer strands are very strong crosslinks that can't be broken by heat |
