Bij een gegeven monomeer of verschillende monomeren moet je zelf een stukje polymeer kunnen tekenen door de monomeren op de juiste manier aan elkaar te plakken. Dat gaat anders bij polyadditie dan bij polycondensatie. Vergeet niet om met een ~ aan te geven dat het om een stukje polymeer gaat. Oefen verder met deze vragen op examenblad.nl. • 2021-2 vraag 30 Geef de structuurformule van een fragment van een additiepolymeer van methylmethacrylaat en styreen. Dit fragment komt uit het midden van de polymeerketen en moet bestaan uit één eenheid methylmethacrylaat en één eenheid styreen. (3p) • 2021-1 vraag 11 Teken een fragment uit het midden van de structuurformule van polyetheen. In het getekend fragment moeten drie monomeereenheden zijn verwerkt. (2p) • 2021-3 vraag 25 Geef de structuurformule van het andere monomeer, dat zorgt voor crosslinks tussen de ketens van het polymeer. (3p) • 2016-2 vraag 10 Geef in structuurformules een gedeelte van een additiepolymeer van acrylzuur. Het weergegeven gedeelte moet komen uit het midden van de polymeerketen en moet bestaan uit drie acrylzuureenheden. (3p) • 2014-1 pilot vraag 23 Geef de structuurformule van een fragment uit het midden van het polymeer PMMA. Dit fragment moet uit drie monomeereenheden bestaan. (3p) • 2012-1 vraag 25 Geef een stukje uit het midden van polypropeen. In dit stukje moeten drie monomeereenheden zijn verwerkt.
