Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications.

Molecular structure of polycarbonate. The Bisphenol A group also contributes to PC’s inability to crystallize. This amorphous structure gives the polymer its particular transparency. PC is most often synthesized from Bisphenol A and phosgene by a step-growth polymerization in which Cl- ions are eliminated every time the monomers react.

2024年5月22日 · Molecular Structure. The backbone of polycarbonate is built from bisphenol A (BPA) and phosgene (COCl2). These two components combine through condensation polymerization, creating long chains that give polycarbonate remarkable properties. Bisphenol A (BPA) BPA is an organic synthetic compound with the formula (CH3)2C(C6H4OH)2.

Structure of polycarbonate Polycarbonates have organic functional groups linked together by carbonate groups (–O–(C=O)–O–). The chemical structure of polycarbonate is shown in the diagram below.

Polymers are macromolecules that are based on a structure built up, chiefly or completely, from a large number of similar structural units bonded together. Often called chains, the polymer consists of repeating units, similar to links.

A polycarbonate molecule consists of bisphenol A and a carbonate group [12]. Bisphenol A has two aromatic rings that have the potential to be used as catalysts for NaCl electrolytes...

2025年1月27日 · Polycarbonate is a polyester in which dihydric (or polyhydric) phenols are joined through carbonate linkages. The general-purpose type of polycarbonate is based on 2,2-bis (4'-hydroxybenzene)propane (bisphenol A) and has the general structure: Polycarbonates are the toughest of all thermoplastics.

Polycarbonate is an amorphous thermoplastic, currently emerging to become one of the fastest-growing engineering plastics due to its unique properties. Its applications in the engineering sector are mainly contributed by the excellent impact strength, toughness, good electrical properties and dimensional stability.

2024年7月25日 · Discover the molecular structure of polycarbonate, a complex polymer known for its amorphous nature and transparency. Learn about its properties and applications.

A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids, the conceptual anhydrides of carbonic acid, or polymers of carbon dioxide.
