Polystyrene is a nonpolar polymer
Polystyrene is a nonpolar polymer that dissolves in nonpolar solvents such as gasoline or benzene. It is also possible to dissolve it in acetone. Acetone is a polar aprotic substance, but due to its two methyl groups (-CH3) and its geometry it is capable of dissolving polymers such as polystyrene or PVC. I am going to show the different types of polystyrene, such as crystal polystyrene, expanded polystyrene (porex, polystyrene, polystyrene, polystyrene, white cork, etc.) or extruded polystyrene and how they dissolve in acetone, turpentine or glue. Recycle plastic.

Polystyrene is a synthetic aromatic polymer made from the monomer styrene. It is a thermoplastic substance that is solid at room temperature. Polystyrene can be rigid or foamed, and it has a variety of applications across different industries.
In its solid form, polystyrene is commonly used in the production of disposable consumer products such as plastic cutlery, CD cases, and packaging materials. It is valued for its low cost, lightweight nature, and ability to be molded into various shapes.
Foamed polystyrene, often referred to as Styrofoam, is widely used as insulation material in construction, packaging material for fragile goods, and as a lightweight filler in products like bean bag chairs and craft supplies.
While polystyrene offers many benefits, it also poses environmental challenges due to its resistance to biodegradation and potential for littering. Efforts to mitigate these issues include recycling programs and the development of alternative materials.
Overall, polystyrene is a versatile and widely used polymer with applications ranging from everyday consumer products to industrial and construction materials.

Acetone is a colorless, volatile liquid organic compound with the chemical formula (CH3)2CO. It is the simplest and smallest ketone molecule. Acetone is highly flammable and has a characteristic odor.
This compound is commonly used as a solvent in various industries, including paint thinners, nail polish removers, and cleaning agents. It is also used in the production of plastics, fibers, and other chemicals. Acetone is miscible with water and many organic solvents, making it a versatile solvent for numerous applications.
In addition to its industrial uses, acetone is also found naturally in the environment. It is produced in small amounts by the human body during metabolism and is excreted in urine and exhaled air.
Acetone is considered relatively safe when used properly, but exposure to high concentrations can cause irritation of the eyes, nose, and throat. It is important to handle acetone with care and in well-ventilated areas.
The concept of polarity in a solvent refers to the distribution of electrical charge within the solvent molecule. A solvent can be polar or nonpolar depending on the arrangement of atoms and the electronegativity of those atoms.
In polar solvents, such as water, the molecules have an uneven distribution of charge, with one end being more negatively charged (due to the presence of electronegative atoms like oxygen) and the other end being more positively charged. This polarity allows polar solvents to dissolve ionic and polar compounds, as they can interact with and surround the charged ions or molecules.
On the other hand, nonpolar solvents, like hexane or carbon tetrachloride, have a more symmetrical distribution of charge, resulting in no significant separation of positive and negative charges within the molecule. Nonpolar solvents are typically used to dissolve nonpolar compounds, as they do not have the ability to interact with charged or polar molecules.
Understanding the polarity of a solvent is essential in various chemical processes, such as dissolution, extraction, and chromatography, as it determines the solubility and interactions between solvents and solutes.
