Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.
[citation needed] Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). [citation needed] PET consists of repeating (C 10 H 8 O 4) units. PET is commonly recycled, and has the digit 1 (♳) as its resin identification code (RIC).

A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols.For example, by introducing other diacids, such as isophthalic acid (IPA), or other diols, such as cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET), the material becomes a copolyester due to its comonomer content.
Allnex was established in 2013 after Advent International acquired the Coating Resins Division as a divestiture from Cytec Industries. [2] In September 2016, Allnex and Nuplex Industries, a global manufacturer of resins, were merged to form one company, which has its corporate center in Frankfurt am Main, Germany.
Alkyd resins are usually classed as long oil, [11] medium oil and short oil. [12] These terms represent the oil length in the resin. [13] Alkyds are also modified with phenolic resin, styrene, vinyl toluene, acrylic monomers (to make them dry more quickly) and isocyanates to produce a polyurethane modified alkyd.
