What is the chemical structure of polyethylene terephthalate?
(C10H8O4)n
Polyethylene terephthalate/Formula
Is polyethylene terephthalate a copolymer?
Polyethylene terephthalate is available as a homopolymer and it can also be modified to produce copolymers (known as PETG or PET-G – polyethylene terephthalate glycol-modified) making it more desirable for a particular application.
What bonds are in polyethylene terephthalate?
The chemical bonds between monomer units are usually covalent bonds which are formed due to addition between some unsaturated monomer units or condensation between two different functional groups such as -COOH, -NH2, -OH etc. The process of formation of polymers from monomer units is called a polymerization process.
What is the formula for polyethylene terephthalate ( PET )?
Polyethylene terephthalate (PET) is a condensation polymer produced by the esterification of ethylene glycol (EG) with terephthalic acid (TPA) or dimethyl terephthalate (DMT) and has the general formula ( OOC C 6 H 5 COOCH 2 CH 2) n.
How is polyethylene terephthalate formed from ethylene glycol?
It is formed by polycondensation of terephthalic acid and ethylene glycol. How is Polyethylene Terephthalate Made? Polyethylene terephthalate which is also abbreviated as PET / PETE is mainly used to manufacture the packaging material for food products such as fruit and drinks containers.
What is the alternative name for polyethylene terephalate?
Alternative Titles: PET, PETE. Polyethylene terephthalate (PET or PETE), a strong, stiff synthetic fibre and resin, and a member of the polyester family of polymers.
What happens to double bond units in polyethylene terephthalate?
Then, the monomer double bond units break and attach with free radicals to form new free radicals. According to the acidic medium, protonation of terephthalic acid happens that reacts with ethylene glycol to form an intermediate that rearranges and due to the transfer of OH- ions forms a polyethylene terephthalate polymer.
