Answer 1

Polyester is hydrophobic

Answer 2

Answer:

c) polyester

Polyester is hydrophobic,

Explanation:

Acrylics, epoxies, polyethylene, polystyrene, polyvinylchloride, polytetrafluorethylene, polydimethylsiloxane, polyesters, and polyurethanes are examples of hydrophobic (water-resistant) polymers.

Polyester fabric is a hydrophobic polymer (poly(ethylene terephthalate)). Its hydrophobic nature can be detrimental in certain applications such as dyeing, finishing, detergency, and so on. Polyester is a widely used material class in material engineering. Polyethylene terephthalate (PET) is classified as highly hydrophobic due to its 0.4 percent moisture regain and lack of polar groups on its backbone.
