PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid. PBAT is produced by many different manufacturers and may be known by the brand names ecoflex , Wango, Ecoworld , Eastar Bio , and Origo-Bi .
Poly(ethylene adipate) or PEA is an aliphatic polyester. [3] It is most commonly synthesized from a polycondensation reaction between ethylene glycol and adipic acid . [ 4 ] PEA has been studied as it is biodegradable through a variety of mechanisms and also fairly inexpensive compared to other polymers. [ 5 ]
Phenol: The phenol used for biochemistry comes as a water-saturated solution with Tris buffer, as a Tris-buffered 50% phenol, 50% chloroform solution, or as a Tris-buffered 50% phenol, 48% chloroform, 2% isoamyl alcohol solution (sometimes called "25:24:1"). Phenol is naturally somewhat water-soluble, and gives a fuzzy interface, which is ...
Terephthalic acid is used as a raw material to make terephthalate plasticizers such as dioctyl terephthalate and dibutyl terephthalate. It is used in the pharmaceutical industry as a raw material for certain drugs. In addition to these end uses, Terephthalic acid based polyesters and polyamides are also used in hot melt adhesives.
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. [2] It is a thermoplastic (semi-)crystalline polymer , and a type of polyester .
Structural formula of the adipate dianion. The anionic (HO 2 C(CH 2) 4 CO 2 −) and dianionic (− O 2 C(CH 2) 4 CO 2 −) forms of adipic acid are referred to as adipates. An adipate compound is a carboxylate salt or ester of the acid. Some adipate salts are used as acidity regulators, including: Sodium adipate (E number E356) Potassium ...
The properties of the phthalate can be varied by changing the alcohol. [6] Around 30 are, or have been, commercially important. Phthalates' share of the global plasticisers market has been decreasing since around 2000 however total production has been increasing, with around 5.5 million tonnes made in 2015, [ 7 ] up from around 2.7 million ...
Polyethylene terephthalate (PET) is a common condensation polymer.. In polymer chemistry, condensation polymers are any kind of polymers whose process of polymerization involves a condensation reaction (i.e. a small molecule, such as water or methanol, is produced as a byproduct).
