Polystyrene is an addition polymer that results when styrene monomers polymerize (interconnect). In the polymerization, the carbon-carbon π bond of the vinyl group is broken and a new carbon-carbon σ bond is formed, attaching to the carbon of another styrene monomer to the chain. Since only one kind of monomer is used in its preparation, it ...

Polystyrene (C8H8)n - Polystyrene is the chemical name of (C8H8)n. Visit BYJUS to study the uses, properties, structure of Polystyrene ((C8H8)n) explained by the chemistry experts.

Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle.

2023年12月13日 · Polystyrene Structure. Polystyrene is a type of vinyl polymer. It consists of a lengthy hydrocarbon chain where every second carbon atom is connected to a phenyl group. It’s manufactured through the free radical polymerization process using the styrene monomer.

2024年12月20日 · Polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. It is widely employed in the food-service industry as rigid trays and containers, disposable eating utensils, and foamed cups, plates, and bowls.

Polystyrene is an odorless, tasteless, rigid thermoplastic. Pure polystyrene has the following structure. The homopolymers of styrene are also referred to as general purpose, or crystal, polystyrene.

The primary structure of polystyrene (molecular weight, stereoregularity, etc.) is dependent on polymerization systems to importantly affect physical and mechanical properties. Free radical polymerization is most widely used to commercially produce atactic polystyrene with

Polystyrene comes in three forms: Syndiatactic, Atactic and Isotactic. They consist of long hydrocarbon chains, with a phenyl group connected to every other carbon atom. The Syndiatactic form is highly regular and crystalline. Atactic polystyrene is irregular and amorphous (disordered) and the Isotactic form is semi-crystaline.

Polystyrene is an optically clear, cheap, easily molded polymer, familiar as the standard “jewel” CD case. In its simplest form, PS is brittle. Its mechanical properties are dramatically improved by blending with polybutadiene, but with a loss of optical transparency.
