Which physical form of polymers can be classified as "dry"?

Polymers can exist in different physical forms depending on their properties and the way they are processed. The term "dry" specifically refers to forms that do not contain significant amounts of solvent or moisture. Granules and powders are characterized by their solid state, making them devoid of any liquid component. This solid form can imply that they are in a dry state, suitable for storage and handling without the risk of spills or evaporation that might occur with liquids.

In contrast, clear liquids, milky solutions, and thick emulsions would all contain liquid components, thus disqualifying them from being classified as "dry." Clear liquids are homogeneous mixtures that are fully liquid, while milky solutions and thick emulsions consist of suspended particulates or droplets within a liquid medium, which also indicates a significant presence of moisture. Therefore, granules and powders represent the only choice that aligns with the definition of dry polymer forms.
