Vwo 6

, 12.1 Kunststoffen op macroniveau
Plastics kun je in alle mogelijke vormen buigen.
- Ze zijn licht, relatief licht en reageren niet met andere stoffen.

Je hebt thermoplasten en thermoharders.
- Thermoharders worden bij verhitting zwart.

In BiNaS 97D staan de recycleersymbolen.

De meest toegepaste techniek voor het scheiden van de kunststofsoorten is
de drijf-zinkmethode.
- Gebaseerd op het verschil in dichtheid.

Granulaat van gerecyclede thermoplasten wordt na smelten tot nieuwe
producten verwerkt.

Thermoharders worden thermische gerecycled.

12.2 Additiepolymeren
Het voorvoegsel ‘poly’ betekend ‘veel’.

Polymeren ontstaan uit monomeren via het proces polymerisatie.

Een polymeer heeft een repeterende eenheid.

Aan moleculen met een C = C binding kan additie plaatsvinden.
- Bij de vorming van polymeren heet dat dan additiepolymerisatie.

Stappenplan structuurformule van polymeer afleiden:

1. Noteer voor de pijl C = C horizontaal.
2. Schrijf de andere atomen of atoomgroepen boven of onder het
bijbehorende C atoom.
3. Noteer na de pijl -C – C – met de andere atomen of atoomgroepen
boven of onder hun C atoom.
4. Plaats vierkante haken en zet er de index ‘n’ achter.
