You are given samples of PVC, exposed to warm cooking oil (90 °F) and acetone. Based on polymer structure, what would you expect to happen to the samples? Why?

What will be an ideal response?


In the polymer structure of polystyrene there is a pendent chlorine atom. This not only prevents the polymer from close packing but also makes it solvent sensitive. The samples would swell with the elevated temperature or water and the polarity of acetone. The free chlorine bonds to the polar water or acetone. The cooking oil wouldn't have this effect as it isn't a polar substance.
