Polyethylene 2,5-furandicarboxylate, also named poly(ethylene 2,5-furandicarboxylate), polyethylene furanoate and poly(ethylene furanoate) and generally abbreviated as PEF, is a polymer that can be produced by polycondensation of 2,5-furandicarboxylic acid (FDCA) and monoethylene glycol (MEG).
 As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN).
 PEF has been described in (patent) literature since 1951, but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based replacement for purified terephthalic acid (PTA) in 2004.
Poloxamer 407 is a hydrophilic non-ionic surfactant of the more general class of copolymers known as poloxamers. Poloxamer 407 is a triblock copolymer consisting of a central hydrophobic block of polypropylene glycol flanked by two hydrophilic blocks of polyethylene glycol.
 The approximate lengths of the two PEG blocks is 101 repeat units while the approximate length of the propylene gycol block is 56 repeat units.
 This particular compound is also known by the BASF trade name Pluronic F127 or by the Croda trade name Synperonic PE/F 127.
Polyethylene glycol–polyvinyl alcohol (PEG-PVA) brand name Kollicoat IR (BASF) is a novel multifunctional excipient used as a pill binder as well as a wet binder.
 The formulation is composed of 25% PEG and 75% PVA; where the vinyl alcohol moieties are grafted on a polyethylene glycol backbone.
Polyethylene glycol (PEG) is a polyether compound with many applications from industrial manufacturing to medicine.
Kolliphor EL, formerly known as Cremophor EL, is the registered trademark of BASF Corp. for its version of polyethoxylated castor oil.
 It is prepared by reacting 35 moles of ethylene oxide with each mole of castor oil.
 The resulting product is a mixture (CAS number 61791-12-6): the major component is the material in which the hydroxyl groups of the castor oil triglyceride have ethoxylated with ethylene oxide to form polyethylene glycol ethers.
 Minor components are the polyethyelene glycol esters of ricinoleic acid, polyethyelene glycols and polyethyelene glycol ethers of glycerol.
 Kolliphor EL is a synthetic, nonionic surfactant used to stabilize emulsions of nonpolar materials in water.
PEG 400 (polyethylene glycol 400) is a low-molecular-weight grade of polyethylene glycol.
 It is a clear, colorless, viscous liquid.
 Due in part to its low toxicity, PEG 400 is widely used in a variety of pharmaceutical formulations.
Cetomacrogol 1000 is the tradename for polyethylene glycol hexadecyl ether, which is nonionic surfactant produced by the ethoxylation of cetyl alcohol to give a material with the general formula HO(CHO)CH.
 Several grades of this material are available depending of the level of ethoxylation performed, with repeat units ("n") of polyethylene glycol varying between 2 and 20.
 If n=20 it is named Brij58.
 If n=10, it is named Brij56.
Polyethylene glycol propylene glycol cocoates or PEG propylene glycol cocoates are chemical compounds produced by the esterification of polyoxyalkyl alcohols with lauric acid.
 Their chemical designation is PEG-8, referring to its polyethylene glycol (PEG) molecular chain length.
Polyether block amide or PEBA is a thermoplastic elastomer (TPE).
 It is known under the tradename of VESTAMID® E (Evonik Industries), and PEBAX (Arkema).
 It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).
 The general chemical structure is:
Maleimide is a chemical compound with the formula HC(CO)NH (see diagram).
 This unsaturated imide is an important building block in organic synthesis.
 The name is a contraction of maleic acid and imide, the -C(O)NHC(O)- functional group.
 Maleimides also describes a "class" of derivatives of the parent maleimide where the N"H" group is replaced with alkyl or aryl groups such as a methyl or phenyl, respectively.
 The substituent can also be a small molecule (such as biotin, a fluorescent dye, an oligosaccharide a nucleic acid), a reactive group, or a synthetic polymer such as polyethylene glycol.
 Human hemoglobin chemically modified with maleimide-polyethylene glycol is a blood substitute called MP4.
