Abstract Polyethylene terephthalate (PET) is the third most widely diffused polymer exploited in the packaging industry, monopolizing the bottles market for beverages, and covering almost the 16% of the European plastic consumption in the packaging industry. Even if PET primarily derived from fossil so...
Process for recovering ethylene glycol from polyethylene terephthalate production A process for recovering column bottom residues produced by distillation of the ethylene glycol resulting from an aromatic polyester production process, consisting of treating said residues with an aromatic mono-alkyl ester and ...
PURPOSE:To obtain the titled solution which is suited for producing an extremely fine, high-strength polyethylene terephthalate fiber by a flash spinning process, by adding polyethylene terephthalate to a specified mixed solvent and dissolving it by heating. CONSTITUTION:Polyethylene terephthalate (A) is...
Polyethylene terephthalate (PET or PETE) is a general-purpose linear semicrystalline thermoplastic polymer. It belongs to the polyester family of polymers. These resins are known for their excellent combination of properties. These properties include mechanical, thermal, and chemical resistance as well as...
During the polymerization process, ethylene glycol and dimethyl terephthalate (C6H4(CO2CH3)2) or terephthalic acid are reacted in the melt state at 150–200 °C with a basic catalyst. As part of the production process, methanol is removed by distillation to drive the reaction forward, and ...
