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 .
Bis(2-ethylhexyl) adipate or DEHA or DOA is an organic compound with the formula (CH 2 CH 2 CO 2 C 8 H 17) 2. It is the diester of 2-ethylhexanol and adipic acid. It is a colorless oily liquid. DEHA is sometimes called "dioctyl adipate", incorrectly. Another name is di(2-ethylhexyl) adipate.
Poly(vinyl alcohol) is one of the few biodegradable vinyl polymers that is soluble in water. Due to its solubility in water (an inexpensive and harmless solvent), PVA has a wide range of applications including food packaging, textiles coating, paper coating, and healthcare products.
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 .
Like other polyesters such as polyethylene terephthalate, two main routes exist for the synthesis of PBS: the trans-esterification process (from succinate diesters) and the direct esterification process starting from the diacid. The direct esterification of succinic acid with 1,4-butanediol is the most common way to produce PBS. It consists of ...
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 ...
