Polystyrene typically exists in an amorphous state, meaning it lacks a crystalline structure. However, at very high pressures or with the addition of certain chemicals, polystyrene can exhibit a crystalline structure with a monoclinic crystal lattice.

Is polystyrene thermosetting or thermoplastic?

Polystyrene is a thermoplastic, which means it softens when heated and can be molded into different shapes but retains its solid structure after cooling.


Why is polystyrene brittle?

Unfilled polystyrene is also known as crystal polystyrene (PS) or general purpose polystyrene (GPPS). However, since crystal polystyrene is brittle, other polymers are added to polystyrene to improve its strength, and copolymers are formed as a result. One such copolymer is high impact polystyrene (HIPS), which is produced by adding polybutadiene rubber to polystyrene during the polymerization process. HIPS is tougher and has a greater impact strength than unfilled polystyrene. There are different types of polystyrene. Extruded polystyrene (XPS) is one form of the polymer that has high tensile strength, with good elasticity. It is commonly known as Styrofoam™. The other common form of polystyrene is expanded polystyrene (EPS). Both EPS and XPS are made from similar materials but there are difference between the two. XPS has a higher density as compared to EPS, due to the absence of air passages between its cells. The higher density makes XPS more rigid and strong. Also, XPS is waterproof and is an effective thermal insulator. Read more in the related link.


Does regifoam produce by polystyrene?

Yes, Regifoam is a type of expanded polystyrene foam commonly used in packaging material and insulation. It is produced from polystyrene resin that is expanded with the help of steam to create a cellular structure, giving it its lightweight and insulating properties.

Which has more crystalline atactic polystyrene or syndiotactic polystyre?

Syndiotactic polystyrene has a more ordered and crystalline structure compared to atactic polystyrene. This is because syndiotactic polymers have a regular alternating arrangement of side groups, allowing them to pack more closely and form a more ordered crystal lattice.
